Description

  The present invention relates to a method of manufacturing a weak current tool such as a weak current sheet or a weak current device that allows a weak current to flow to the skin or the like.

  There are a wide range of therapies to promote health by applying weak current to human skin. It is said that the natural healing power of humans is enhanced by giving appropriate weak current to human body. As a treatment that focuses on that, microcurrent therapy is mentioned. Microcurrent therapy promotes generation of ATP (adenosine triphosphate) enzyme necessary for wound repair and protein synthesis by artificially applying a weak current externally. Microcurrent therapy is said to be particularly effective in treating trauma. In addition, although it is not intended for treatment of trauma, by applying a weak current to human skin, the disorder of the biocurrent originally flowing in the human body is corrected, and the ion arrangement of human cell tissue is adjusted. This is also widely used to help prevent and cure disease. As such a weak current treatment device, various weak current generating devices have been developed and commercialized.

  In Patent Document 1, a metal electrode having a potential higher than a standard unipolar potential and a semiconductor electrode having a potential lower than the standard unipolar potential are electrically connected, and the metal electrode and the semiconductor electrode are applied to human skin to obtain a weak current There is described an element for transdermal drug delivery.

  In Patent Document 2, a piezoelectric body is provided in a flat plate shape on a substrate having elasticity and conductivity, and the substrate and the piezoelectric body are fixed to the surface of a human body by an adhesive sheet or a supporter, and pressure is applied to the piezoelectric body to generate weak current. A weak current treatment device is described which energizes the skin.

  In the following, as an example of a weak current tool, a weak current tool having a sheet-like weak current sheet to be used by sticking to a human body and a handle portion to be pressed against the human body will be described as an example. Not limited to this. What is necessary is to have the above configuration and to be used in contact with the human body.

<Weak current sheet>
FIG. 1 is a view showing an example of a weak current sheet which is an example of the weak current tool according to the present invention. FIG. 2 is a view showing an example of a base and an adhesive tape used therein, and FIG. 4 is a view for explaining an example of its use state. FIG. 3 is a view showing a conventional weak current tool. 5 to 7 are views showing the configuration of the weak current sheet and an example of a cross-sectional view.

  FIG. 1 is a plan view of a weak current sheet 100 according to the present invention and is a view looking down on a skin contact surface 101 which is a surface contacting a human skin. The weak current sheet 100 at least includes a positive electrode portion 110, a negative electrode portion 120, and an insulating portion 150. The positive electrode portion 110 and the negative electrode portion 120 are made of different metals having a potential difference. The positive electrode portions 110 and the negative electrode portions 120 appear alternately on the skin contact surface 101. The insulating portion 150 is made of an insulating material, and is located between the positive electrode portion 110 and the negative electrode portion 120 on the skin contact surface 101 to insulate the positive electrode portion 110 from the negative electrode portion 120.

  For convenience of explanation, although an example in which the weak current sheet 100 includes one positive electrode portion 110 and two negative electrode portions 120 located on both sides thereof will be described below, including the illustration, the positive and negative electrode portions are Needless to say, they may appear alternately, and may be included in plural.

  In addition, the insulating portion may be formed in a planar shape having a plurality of windows, and the positive and negative electrode portions may be exposed to the skin contact surface from the plurality of windows. The window part should just penetrate an insulation part in the thickness direction, and not only a rectangle but a circle, an ellipse, a triangle, a polygon, etc. may be sufficient as it.

  The weak current sheet 100 is used, for example, by placing the skin contact surface 101 on the affixing surface of the affixing tape 170 and affixing the affixing tape 170 to a human body. The bonding tape 170 may be provided with an adhesive or the like on the entire bonding surface on which the weak current sheet 100 is mounted, and the weak current sheet 100 may be bonded thereto, or in the mounting area of the weak current sheet 100. No adhesive or the like is provided, and an adhesive or the like may be provided only around the periphery.

  The sticking tape 170 may have stretchability. Thereby, the adhesion to the skin surface of the human body can be enhanced. Moreover, the sticking tape 170 may be stuck not on the whole back surface (surface on the opposite side of a skin contact surface) of the weak current sheet 100 but only on a part, for example, only on both sides. Moreover, the sticking tape 170 may be pressed by another member, for example, a supporter etc., and may be comprised as a part of supporter. The adhesive tape 170 may be pressed by using an elastic rubber material or may be attached to the human body by providing attachment holes on both sides.

  As shown in FIG. 2, a base 160 may be provided on the affixing surface of the affixing tape 170, and the weak current sheet 100 may be installed on the base 160 and may be installed on the affixing surface of the affixing tape 170 via this. It is preferable that the base 160 be flexible and the weak current sheet 100 be adapted to the target site of the human body.

  For the base 160, for example, silicone rubber, a plastic resin, a foamed resin such as polyurethane, or the like is used. Also, materials such as cloth, paper, wood and the like may be used. By using a breathable material, it is possible to prevent stuffiness.

  In addition, fine irregularities (for example, fine press, patterns due to corrosion, surface processing such as sand blast, etc.) or fine through holes (for example, laser, punching, etc.) on the upper surface (skin contact surface side) of positive and negative electrode parts ) May be given to provide breathability.

  Fig.3 (a) is a figure which shows the cross section of the conventional weak current tool 900, FIG.3 (b) is the use condition figure. The positive electrode portion 910 and the negative electrode portion 920 of the weak current tool 900 are provided on the tip of the projection 970 by plating or painting. The distance between the positive and negative electrode portions and the electrode portion of the weak current tool 900 is small, the width m91 of the positive electrode portion 910 and the width m92 of the negative electrode portion 920 are each 1 mm or less, and the distance d91 between them is 1 mm It is below. In addition, although not shown in the figure, a weak electric current tool of a type in which particles are provided with positive and negative electrode parts is finer, and the distance between particles is 100 μ or less.

  As shown in FIG. 3 (b), the skin of the human body p1 includes an epidermis p11, a dermis p12 and a subcutaneous tissue (superior fascia) p13. The thickness of the epidermis p11 is about 0.1 mm to 0.2 mm on average, and the thickness of the dermis p12 is about 1.0 mm to 3.0 mm on average. The subcutaneous tissue p13 varies depending on the site. The thickness is said to be about 2 mm, and about 4 mm to 9 mm elsewhere. Since many of muscle p20 (including deep fascia p21, epimyocardium p22, and perimysium p23) and nerves are located under the skin, their action must be performed through the skin.

  The conventional weak current tool 900 has a narrow gap between the positive and negative electrodes and weak weak current q91, so its action remains on the skin as shown, and does not reach the muscle etc. under it (q1 can not be expected) ).

  On the other hand, in the weak current sheet 100 according to the present invention, the width m1 of the exposed portion of the positive electrode portion 110 is about 2 mm to 15 mm in the X direction (the direction in which the positive and negative electrode portions appear alternately) More preferably, it is 3 mm to 12 mm. In addition, the width m2 of the exposed portion of the negative electrode portion 120 is approximately 3 mm to 25 mm, and more preferably 4 mm to 20 mm. The distance between the exposed portion of the positive electrode portion and the exposed portion of the negative electrode portion is equal to the width d1 of the insulating portion 150 and is about 3 mm to 15 mm, more preferably 4 mm to 10 mm.

  In the weak current sheet 100, the width of the exposed portions of the positive and negative electrode portions on the skin contact surface is wide, and the distance between the exposed portions of both electrode portions is also wide. Therefore, as shown in FIG. 4, the weak current q1 by the weak current sheet 100 also reaches the muscle under the skin and the tissues such as the fascia and nerve. In addition, because the width of the exposed portion of the electrode portion is wide, even if the central portion can not be attached to a proper point, the peripheral portion can be covered, which is easy to use even for users who do not have specialized knowledge.

  FIG. 5 (a) is a cross-sectional view showing an example of the configuration of the weak current sheet 100, and FIG. 5 (b) is a partially enlarged view thereof. As illustrated, the weak current sheet 100 may have a conductive portion 130, and the positive electrode portion 110 and the negative electrode portion 120 may be mounted on the top surface of the conductive portion 130. There are at least one positive electrode portion 110 and at least one negative electrode portion 120, and the positive electrode portion 110 and the negative electrode portion 120 are alternately mounted on the conductive portion 130 (upper surface). The positive electrode portion 110 and the negative electrode portion 120 are spaced apart, and in the state where the insulating portion 150 is not provided, the conductive portion 130 is exposed from the gap between the two.

  The positive electrode portion 110 and the negative electrode portion 120 are made of a metal material mainly composed of different metals having a potential difference. The positive electrode portion 110 is, for example, gold (Au +), atomic weight 197.2, standard electrode potential is +1.50 volts, and the negative electrode portion is, for example, aluminum (Al +++) atomic weight 26.97, standard electrode potential is −1.337. Bolt, zinc (Zn ++) atomic weight 65.38, standard electrode potential -0.762 volts. The above is an example, and when the metal itself is oxidized to form an oxide film like aluminum, the potential may be different from the potential indicated by the standard electrode potential. In addition, the amount of current generated varies depending on the arrangement distance between the two electrodes, the area of the electrodes, the degree of adhesion of the skin, and the condition.

  The conductive portion 130 may have conductivity, and may be a film or a sheet (including a mesh or grid) made of metal (including one containing metal powder), or conductive having conductivity. An adhesive (including a paint having adhesiveness) may be used.

  The insulating unit 150 is made of an insulating material and may be in the form of a sheet. For example, it is possible to cut and stick a tape such as nylon or vinyl having tackiness. Also, it may be a film or a layer. For example, it may be formed by painting or printing. The insulating unit 150 includes at least a first insulating unit 151 that insulates the positive electrode unit 110 and the negative electrode unit 120 on the skin contact surface.

  The first insulating portion 151 is adjacent to a first covering portion 1511 covering the edge of the positive electrode portion 110, a second covering portion 1512 covering the edge of the negative electrode portion 120, and the electrode portion of the conductive portion 130. And a covering third portion 1513. The first insulating portion 151 straddles the ridge 102 of the positive electrode portion 110 and the conductive portion 130 and covers the adjacent portion of the first covering portion 1511 and the conductive portion 130 covering the edge portion of the positive electrode portion. The third covering portion 1513 is formed, and the second covering portion 1512 covering the edge portion of the negative electrode portion is formed adjacent to the conductive portion 130 so as to cover the ridge 103 of the negative electrode portion 120 and the conductive portion 130. It can be said that a third covering portion 1513 which covers the portion is formed.

  Thus, the first insulating portion 151 covers not only the conductive portion exposed between the positive and negative electrode portions but also the edge portions of the positive and negative electrode portions. This is because current may be released at the edge of the electrode part, and if sweat adheres, it is likely to cause a short circuit, resulting in loss of current and redness of the skin when used for a long time. This is to prevent the edge of the part from coming into direct contact.

  The insulating portion 150 may further include a second insulating portion 152 located at the edge of the skin contact surface 101. The second insulating portion 152 covers at least a part of the edge portion of the electrode portion located at the edge portion of the weak current sheet from above, and covers the outer edge portion 121 of the negative electrode portion 120 here.

  FIG. 6 (a) is a cross-sectional view showing an example of the configuration of the weak current sheet 100, and FIG. 6 (b) is another example. As shown in FIG. 6A, in the weak current sheet 100, one of the positive electrode portion and the negative electrode portion may double as the conductive portion.

  When the positive electrode portion 110 is formed of gold and the negative electrode portion 120 is formed of a metal such as zinc, titanium, or aluminum, a portion of the negative electrode portion 120 also serves as a conductive portion. Alternatively, when the positive electrode portion 110 is formed of gold, silver, copper or the like, part of the positive electrode portion 110 may double as the conductive portion.

  Hereinafter, a configuration in which a part of the negative electrode portion 120 doubles as a conductive portion will be described as an example. The positive electrode portion 110 is mounted on the negative electrode portion 120 which also serves as a conductive portion. The first insulating portion 151 insulates the positive electrode portion 110 and the negative electrode portion 120, and includes a first covering portion 1511 and a third covering portion 1513. That is, the first insulating portion 151 covers the edge 102 of the positive electrode portion 110 so as to cover the ridge 102 of the positive electrode portion 110 and the negative electrode portion 120, and the negative electrode portion 120. And a third covering portion 1513 covering an adjacent portion of Since the first insulating portion 151 not only insulates the positive and negative electrode portions but also covers the edge portion of the positive electrode portion, the edge portion of the electrode portion can be prevented from coming into direct contact with the skin contact surface.

  As shown in FIG. 6 (b), the outer edge 121 of the negative electrode portion 120 may be formed to be located inside the edge of the base 160. The second insulating portion 152 covers the outer edge portion 121 of the negative electrode portion 120 (first covering portion 1521) and also covers the edge portion of the base portion 160 therebelow (second covering portion 1522). This prevents the edge of the electrode portion from coming into direct contact with the skin even at the edge of the skin contact surface.

  FIG. 7 is a cross-sectional view showing an example of the configuration of the weak current sheet 100. As shown in FIG. As illustrated, the weak current sheet may have a conductive portion 130, and the positive electrode portion 110 may be placed on the negative electrode portion 120 via the conductive portion 130. The conductive portion 130 is, for example, a conductive adhesive, and may have an effect of fixing and connecting the positive electrode portion 110 to the negative electrode portion 120. Furthermore, the overcurrent can be prevented by providing the conductive portion 130 with a certain resistance value.

<Weak current equipment>
FIG. 8 is a view showing an example of a weak current device which is an example of the weak current device according to the present invention. FIG. 9 is a view showing the skin contact surface. The illustrated weak current device has a cylindrical base portion and is rotatably connected to the handle as described later, but the weak current device has a plate-shaped base portion on the opposite side of the skin contact surface to the handle portion. It may be fixed and connected by a surface. The differences from the weak current sheet will be mainly described below.

  The weak current device 200 includes a positive electrode portion 210, a negative electrode portion 220 also serving as a conductive portion, and an insulating portion 250, and contacts the skin at the skin contact surface 201 configured of these to flow a weak current. The positive electrode unit 210, the negative electrode unit 220 and the insulating unit 250 are installed on the base 260.

  The base portion 260 has a substantially cylindrical shape, and is rotatably connected to the handle portion 270 through a holding hole penetrating the center of the cylindrical shape. The positive and negative electrode portions and the insulating portion are disposed on the circumferential surface of the base 260.

  The handle portion 270 includes a rod-like portion extending in the Y direction which is the gripping direction of the user, and a holding portion 271 which is a portion extending in the X direction substantially perpendicular to the Y direction from the tip of the rod portion. The holding portion 271 has a rod-like holding shaft at its tip, and the holding hole of the base 260 is inserted through the holding shaft. The handle portion 270 includes a separate stopper 272, and after inserting the base 260 into the holder 271, the holder 272 is connected to the tip of the holder shaft so that the base 260 is not detached from the holder. You may stop. The stopper 272 is, for example, provided with a female screw inside, and is screwed and connected with a male screw provided at the tip of the holding shaft of the holding portion 271.

  In the weak current device 200, the negative electrode portion 220 covers the substantially central portion of the circumferential surface of the base portion 260 in the circumferential direction and covers the substantially central portion of the negative electrode portion 220 such that the positive electrode portion 210 is wound in the circumferential direction. There is. As a result, the negative electrode portion 220 also serving as the conductive portion is disposed on the base portion 260, and the positive electrode portion 210 is disposed on the negative electrode portion 220. Here, although an example in which one positive electrode portion 210 is provided is illustrated, two or more positive electrode portions may be provided side by side on one negative electrode portion, or a plurality of negative electrode portions may be provided. The positive electrode portion may be provided substantially at the center.

  In addition, the first insulating portion 251 is provided in the circumferential direction so as to cover the ridges 202 of the positive electrode portion 210 and the negative electrode portion 220. Furthermore, the second insulating portion 252 is also provided in the circumferential direction in a band shape so as to cover the ridge 204 of the outer edge portion 221 of the negative electrode portion 220 and the base portion 260.

  That is, as shown in FIG. 9, the first insulating portion 251 covers the edge of the positive electrode portion 210 so as to cover the ridge 202 of the positive electrode portion 210 and the negative electrode portion 220. A first covering portion 2511 and a third covering portion 2513 covering an adjacent portion of the negative electrode portion 220 are included. In addition, the second insulating portion 252 covers the rim 204 of the negative electrode portion 220 and the base portion 260 so as to cover the first covering portion 2521 covering the outer edge portion 221 and the second portion covering the adjacent portion of the base portion 260. And a covering portion 2522.

  The width of the exposed portion of the positive and negative electrode portions in the X direction and the width of the insulating portion are the same as described above. Similar to the weak current sheet 100, in the weak current device 200, the width of the exposed portions of the positive and negative electrode portions on the skin contact surface is wide, and the distance between the exposed portions of both electrode portions can be wide. Therefore, the weak current can be delivered also to the muscle under the skin, its fascia, and tissues such as nerves. In addition, because the width of the exposed portion of the electrode portion is wide, the peripheral portion can be covered even if the central portion thereof is not applied to an appropriate point, so it is easy to use for a user who does not have specialized knowledge.

  In addition, as described above, the weak current device 200 has a structure in which the other electrode portion is disposed on one of the electrode portions also serving as the conductive portion and the crucible is covered with the insulating material, so that it can be easily formed. . In addition, by installing the electrode unit on the rotatable base, the skin contact surface is located on the rotation circumferential surface, and the user can easily bring the skin contact surface into a wide range of skin without changing the posture. Can.

  The weak current device 200 may be of a replaceable type. That is, the positive and negative electrode parts and the insulating part, which are the acting parts, may be stuck on the base with an adhesive or a surface fastener. At this time, the action part may be provided in a sheet form and attached to the base.

  In addition, by forming the peripheral surface of the base with a flexible material, the skin contact surface can be easily adapted to the skin, can be easily fitted, and the range in which the weak current can reach can be deepened. Alternatively, the same effect can be obtained by placing a flexible material on the circumferential surface of the base and placing the electrode portion thereon.

In addition, although a 1st metal material is demonstrated as a positive electrode material and a 2nd electrode material below as a negative electrode material, as long as it does not contrary to the main point of this application, the opposite may be sufficient. Hereinafter, the method of manufacturing the weak current tool will be described by taking the weak current sheet 100 and the weak current device 200 as an example.

In the manufacture of the weak current sheet 100, first, an electrode combination material including a positive electrode material and a negative electrode material is manufactured. In the case where the positive and negative electrode parts are connected via the conductive part, an electrode bonding material including the positive and negative electrode materials and the conductive material is manufactured. Next, an insulating material is placed on the electrode bonding material and punched into a predetermined shape to manufacture a weak current sheet. As described later, after the electrode bonding material is punched out, an insulating material may be installed to manufacture a weak current sheet.

<Production Example 1 of Electrode Bonding Material>
FIG. 10 is a view for explaining an example of the production of the electrode bonding material.

<Positive electrode material>
The positive electrode material 1 is formed by, for example, extending a plate material of gold, silver, copper or the like to a predetermined thickness by rolling. After rolling, annealing may be performed as needed. The predetermined thickness is, for example, 10 μ.

  Basically, in rolling, a plurality of rolling and then both sides are cut off in a uniform width, and the rolling is repeated to obtain a predetermined thickness and to cut both sides into a predetermined width. When it hardens in the meantime, annealing is performed suitably.

  Moreover, the positive electrode material 1 may mix not only pure gold but silver or copper. Gold may be mixed with 2 to 20% of silver or copper. Preferably, an alloy in which 5 to 15% of silver is mixed with gold has good gloss and processability. Here, although the other ingredients may be included to some extent, the proportions of the main materials are described.

<Negative electrode material>
The negative electrode material 2 is formed by rolling a plate material such as titanium, zinc, or aluminum to a predetermined thickness. After rolling, annealing may be performed as needed. The predetermined thickness is, for example, 100 μ.

<Electrode bonding material>
First, the positive electrode material 1 is placed on the negative electrode material 2 to form a stacked material 4. Here, the positive electrode material 1 may be placed on the negative electrode material 2 via a conductive adhesive (including a paint having adhesiveness).

  Next, the overlapping material 4 is stretched to a predetermined thickness by rolling to manufacture the electrode bonding material 40. The predetermined thickness is, for example, 10 μ. By rolling, the positive and negative electrode materials having a length L1 become an electrode bonding material 40 having a length L2. For example, the length L2 is 10 to 20 times the original length L1. Note that depending on the materials of the positive electrode material 1 and the negative electrode material 2, both sides may spread slightly by rolling, and the width may be wide.

  The positive electrode material 1 may be plated (for example, gold plated). For example, the positive electrode material 1 may be disposed on the negative electrode material 2 by masking both ends in the width direction of the negative electrode material 2 and performing gold plating, and may be used as the overlapping material 4.

  In a weak current sheet, when the positive electrode portion and the negative electrode portion are spaced apart and the negative electrode portion is electrically connected to the positive electrode portion via the conductive portion, the electrode bonding material is a conductive material. Including. In that case, the positive electrode material 1 and the negative electrode material 2 are placed on the conductive material, and then rolling is performed by rolling to manufacture an electrode bonding material.

<Modification 1>
As shown in FIG. 11, after the rolling process, the negative electrode material may be grooved at the installation position of the positive electrode material 1 to form the negative electrode material 2a having the installation groove 21a. The positive electrode material 1 is fitted into the installation groove 21a of the negative electrode material 2a to form a laminated material, which is rolled and manufactured to produce an electrode bonding material. By providing the installation groove, the installation position of the positive electrode material 1 can be easily determined, and the positional deviation of the positive electrode material can be prevented.

Further, by rolling, the degree of adhesion between the negative electrode material 2a and the positive electrode material 1 is increased, and diffusion bonding between metals takes place, making it difficult to peel off. Melt bonding can promote stronger bonding by increasing adhesion and applying a high temperature of 500 ° C. or higher (within the range in which both metals do not melt). For example, in the case of bonding gold and titanium, it is heated and rolled at about 600.degree.
Furthermore, since precious metals are expensive, in order to reduce the amount of use of the positive electrode material 1, other metals may be laid underneath to obtain a clogged structure. For example, silver or copper may be placed under the gold.

  The positive electrode material 1 may be plated (for example, gold plated). The overlapping material 4 can be formed by masking portions other than the installation groove 21a and filling the installation groove 21a with gold plating. In this case, for example, the positive electrode material is formed on the groove wall of the installation groove 21a in the process of rolling into the electrode bonding material 40 by rolling the positive electrode material mainly containing gold and the negative electrode material mainly containing titanium. Because it is blocked and it is difficult to spread laterally, it can be stretched precisely in the longitudinal direction.

<Modification 2>
As shown in FIG. 12, after the rolling process, the negative electrode material may be roughened by scratching the surface at the installation position of the positive electrode material 1 or the like to form the negative electrode material 2b having the rough surface 22b. . The surface roughening may be scribing, sand blasting, hair line processing, chemical polishing, or the like, or removal of the oxide film on the surface. By providing the rough surface 22b, the affixing of the positive electrode material to the negative electrode material becomes stronger. Roughening may be performed on the entire top surface of the negative electrode material 2b. This can prevent the negative electrode portion from sticking to the skin.

  Moreover, in order to facilitate the application of the positive electrode material to the negative electrode material, a conductive paint, a volatile solvent, a varnish, lacquer, etc. may be used. Alternatively, a soft metal such as tin may be placed in the form of powder, linear or mesh.

  Although not shown, a pressing jig may be used for rolling the electrode bonding material. The pressing jig is disposed between the positive electrode material and the negative electrode material, and the adhesion is adjusted by changing the elongation rate and hardness or changing the surface processing between the positive electrode material side and the negative electrode material side. May be

FIG. 13 is a view for explaining another example of the production of the electrode bonding material.

<Negative electrode material>
The negative electrode material 20c is formed by rolling a plate material such as titanium or zinc to a predetermined thickness. After rolling, annealing may be performed as needed. The predetermined thickness is, for example, 10 μ. For example, in the case of titanium, when 1 kg of titanium is extended to about 120 mm in width and about 10 μ in thickness, it becomes about 180 m in length, and when extended to about 60 mm in width and about 10 μ in thickness, it becomes about 360 m in length. The predetermined thickness is more preferably 4 μ to 8 μ.

<Electrode bonding material>
By bonding the positive electrode material 10c such as gold foil to the negative electrode material 20c, an electrode bonding material 40c is manufactured. For bonding, an adhesive or the like having conductivity is used. At this time, the current can be adjusted to a predetermined width by giving a predetermined resistance to the applied adhesive or the like.

<Production Example 3 of Electrode Bonding Material>
FIG. 14 is a view for explaining another example of the production of the electrode bonding material of the weak current sheet material.

<Mounting>
A roll-shaped base 80d having a predetermined length and a predetermined width is prepared.

<Negative electrode material>
By coating (covering) particles of titanium, aluminum, silver and the like together with a binder on the base paper 80d, the negative electrode material 20d (negative electrode layer 20d) is formed (placed). The air permeability of the coated surface may be enhanced by mixing particulate materials such as foam, cloth, wood, paper and the like with the binder. Alternatively, a conductive adhesive (including a paint having adhesiveness) may be applied to the backing sheet 80d, and the above coating may be performed thereon.

<Electrode bonding material>
An electrode bonding material 40d is manufactured by sticking a positive electrode material 10d such as a gold foil on the negative electrode material 20d. For bonding, a conductive adhesive or a conductive double-sided tape is used. Alternatively, the positive electrode material 10d (positive electrode layer 10d) is disposed on the negative electrode material 20d by coating pure gold powder (gold powder) or the like, and the electrode bonding material 40d is manufactured. Here, the electrode bonding material 40d is formed into a roll and used in the next step. The electrode bonding material can be processed sequentially from the end while being pulled out of the roll.

  The negative electrode material can be the one shown in FIG. 6 when it is placed on the entire surface of the backing sheet coated with the conductive adhesive as shown. On the other hand, a plurality of belts may be provided at predetermined intervals. Then, the positive electrode material 10d may be disposed between the adjacent negative electrode materials at a predetermined interval, and the positive and negative electrode materials may be alternately spaced and arranged. Then, the one shown in FIG. 5 can be obtained.

  In addition, if materials, such as cloth, paper, and wood, are used for the mount, it becomes an air-permeable, electrode-friendly material that is gentle on the skin.

  In addition, the electrode bonding material is coated (covered) with particles of titanium, aluminum, silver and the like together with a binder on a base 80 d to which a conductive adhesive is applied, and a negative electrode material 20 d (negative electrode layer 20 d) The positive electrode material 10d (negative electrode layer 20d) may be formed (placed) by coating (covering) particles of gold or the like together with a binder.

Here, printing is performed such that both sides in the width direction of the positive electrode material are covered with the insulating material 50 b so that the positive electrode region 41 is located between the two negative electrode exposed regions.

In addition, it is possible to apply and apply to the slightly concave portion or slightly protruding portion of the human body with the roundness and the slightly wide width. In addition, since it is symmetrical, it can be stuck across two muscles.
