Description

The present invention relates to wiring sheets.

In some cases, the planar heater is required to keep warm only the part touched by a person, for example. For example, Patent Literature 1 describes a planar heater comprising a plurality of electrode portions each comprising a pair of electrode components facing each other at a constant interval, and a heating element. In this planar heater, the parts other than the electrode part form a double-structure woven structure.

However, in the planar heater disclosed in Patent Document 1, a woven structure is used to achieve the pressure-sensitive switch function. In addition, since the woven structure cannot be eliminated, for example, the planar heater cannot be made transparent, and there is a problem that the degree of freedom in design is low.
On the other hand, in the planar heater, it may be required to set the temperature for each location within the sheet plane. The planar heater described in Patent Document 1 cannot meet such requirements.

[First embodiment]
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described with reference to the drawings, taking an embodiment as an example. The invention is not limited to the content of the embodiments. In the drawings, some parts are enlarged or reduced for ease of explanation.

(wiring sheet)
As shown in FIGS. 1, 2, 3, and 4, the wiring sheet 100 according to the present embodiment has a first base material 1 and a plurality of first conductive linear bodies 21 arranged at intervals. A first pseudo sheet structure 2, a first resin layer 3, a first electrode 41, a second electrode 42, a spacer member 5, a second base material 6, and a plurality of second conductive linear bodies 71. are arranged at intervals, and a second resin layer 8.
The first electrode 41 and the second electrode 42 are paired. Also, the first electrode 41 is electrically connected to one or more of the first conductive linear bodies 21 . The second electrode 42 is electrically connected to one of the first conductive linear bodies 21 that is not electrically connected to the first electrode 41 . On the other hand, the second electrode 42 is not electrically connected to one of the first conductive linear bodies 21 that is electrically connected to the first electrode 41 .
The spacer member 5 is arranged between the first pseudo-sheet structure 2 , the first electrode 41 and the second electrode 42 , and the second pseudo-sheet structure 7 . Therefore, the second pseudo-seat structure 7 is spaced apart so as to face the first pseudo-seat structure 2 and is not electrically connected to the first electrode 41 and the second electrode 42 .
The volume resistivity of first conductive linear body 21 is smaller than the volume resistivity of second conductive linear body 71 . In addition, in a plan view of wiring sheet 100, first conductive linear bodies 21 and second conductive linear bodies 71 intersect at respective intersections.
When the first pseudo-sheet structure 2 and the second pseudo-sheet structure 7 are electrically connected, the resistance value is different between any of the second conductive linear bodies 71 between the intersections. ing.

In the wiring sheet 100 according to this embodiment, the volume resistivity of the first conductive linear bodies 21 is lower than the volume resistivity of the second conductive linear bodies 71 . Therefore, when first conductive linear body 21 and second conductive linear body 71 are electrically connected, heat generation in first conductive linear body 21 can be reduced, and second conductive linear body 71 can be Heat generation in the body 71 can be increased. It should be noted that heat generation by the second conductive linear body 71 can more appropriately generate heat in the portion corresponding to the pressurized portion.

In the wiring sheet 100 according to the present embodiment, since the resistance value is different between any of the second conductive linear bodies 71 between the intersections, it is possible to change the amount of current between the intersections. can. By changing the amount of current between intersections, the amount of heat generated can be adjusted for each location on the sheet plane, so the temperature can be set for each location on the sheet plane.

Here, as a method for changing the resistance value between the second conductive linear bodies 71 between the intersections, for example, the following method can be used.
For example, as shown in FIG. 2, the spacing between any of the first conductive linear bodies 21 may be different.
When the intervals L1 of the first conductive linear bodies 21 are different, the lengths of the second conductive linear bodies 71 between the intersections are different. In that case, if the material and thickness of the second conductive linear bodies 71 are the same, the resistance values of the second conductive linear bodies 71 between the intersections will be different. Then, as shown in FIG. 2, when the interval L1 between the first conductive linear bodies 21 becomes longer toward the ends, the resistance value of the second conductive linear bodies 71 between the intersections is becomes higher as it approaches . Therefore, the amount of current flowing through the second conductive linear body 71 between the intersections becomes smaller toward the ends.

As shown in FIG. 3, any one of the second conductive linear bodies 71 may have a different thickness.
The resistance value of the second conductive linear body 71 becomes lower as the thickness (diameter) D2 of the second conductive linear body 71 becomes thicker if the material is the same. Then, as shown in FIG. 3, when the thickness of the second conductive linear body 71 becomes thicker toward the center, the resistance value of the second conductive linear body 71 between the intersections is It gets lower as you get closer to the edge. Therefore, the amount of current flowing through the second conductive linear body 71 between the intersections increases toward the central portion.

The material may be different between any of the second conductive linear bodies 71 .
The resistance value of the second conductive linear body 71 can be changed according to the material by changing the material. For example, the higher the volume resistivity of the material used for the second conductive linear bodies 71, the higher the resistance value of the second conductive linear bodies 71 between the intersections.

In the wiring sheet 100 according to the present embodiment, when the second pseudo sheet structure 7 is in a state where no stress is applied in the direction from the second pseudo sheet structure 7 toward the first pseudo sheet structure 2, the first pseudo sheet structure Contact with the first pseudo-seat structure 2 when it is not in contact with the seat structure 2 and stress is applied in the direction from the second pseudo-seat structure 7 toward the first pseudo-seat structure 2 is preferred.
With such a structure, when a hand or the like touches a portion of wiring sheet 100 and stress is applied, first conductive linear bodies 21 and second conductive linear bodies 71 are electrically connected. There is a connection point that connects If there are two or more connection points, electricity can flow between the connection points. Heat can be generated in the range where the current is applied in this manner. On the other hand, in the range where no stress is applied, there is no connecting point, so no electricity is supplied and no heat is generated. In this manner, the wiring sheet 100 can selectively generate heat at the portion that is pressed by a hand or the like. That is, the wiring sheet 100 has a pressure-sensitive function and a heat-generating function. Note that the pressure-sensitive function is a function of selectively energizing a portion to which pressure is applied.

(Base material)
The first substrate 1 can support the first pseudo-sheet structure 2 directly or indirectly. The second substrate 6 can support the second pseudo-sheet structure 7 directly or indirectly. Note that the first base material 1 and the second base material 6 do not necessarily have to be provided. The first base material 1 and the second base material 6 are members provided as needed.
Examples of the first base material 1 and the second base material 6 include synthetic resin film, paper, nonwoven fabric, cloth, and glass film. The first base material 1 and the second base material 6 are preferably transparent base materials or base materials having visibility. With such a configuration, the wiring sheet 100 can be transparent or have visibility.
Also, the first base material 1 and the second base material 6 may be stretchable base materials. For example, if the first base material 1 is a stretchable base material, the stretchability of the wiring sheet 100 can be ensured even when the first pseudo sheet structure 2 is provided on the first base material 1 .
As the first base material 1 and the second base material 6, a synthetic resin film, a nonwoven fabric, a cloth, or the like can be used.
Examples of synthetic resin films include polyethylene film, polypropylene film, polybutene film, polybutadiene film, polymethylpentene film, polyvinyl chloride film, vinyl chloride copolymer film, polyethylene terephthalate film, polyethylene naphthalate film, and polybutylene terephthalate film. , polyurethane film, ethylene vinyl acetate copolymer film, ionomer resin film, ethylene/(meth)acrylic acid copolymer film, ethylene/(meth)acrylic acid ester copolymer film, polystyrene film, polycarbonate film, and polyimide film etc. In addition, stretchable substrates include these crosslinked films and laminated films.

Fabrics include, for example, woven fabrics and knitted fabrics. Paper, non-woven fabric, and cloth as stretchable substrates are not limited to these.
The thickness of the elastic base material is not particularly limited. The thickness of the stretchable substrate is preferably 10 μm or more and 10 mm or less, more preferably 15 μm or more and 3 mm or less, and even more preferably 50 μm or more and 1.5 mm or less.

(pseudo sheet structure)
The first pseudo sheet structure 2 has a structure in which a plurality of first conductive linear bodies 21 are arranged at intervals. Also, the first pseudo sheet structure 2 is arranged in a plurality in a direction intersecting with the axial direction of the first conductive linear body 21 .
Similarly, the second pseudo sheet structure 7 has a structure in which a plurality of second conductive linear bodies 71 are arranged at intervals. The second pseudo sheet structure 7 has a structure in which a plurality of second conductive linear bodies 71 are arranged in a direction intersecting the axial direction of the second conductive linear bodies 71 .

The first conductive linear bodies 21 and the second conductive linear bodies 71 may be linear or wavy in a plan view of the wiring sheet 100 . Wave shapes include, for example, sine waves, rectangular waves, triangular waves, and sawtooth waves. For example, if the first pseudo-sheet structure 2 has such a structure, when the wiring sheet 100 is stretched in the axial direction of the first conductive linear bodies 21, the first conductive linear bodies 21 Disconnection can be suppressed.

The volume resistivity of the first conductive linear body 21 is preferably 1.0×10 ⁻⁹ Ω·m or more and 1.0×10 ⁻⁵ Ω·m or less, and preferably 5.0×10 ⁻⁹ Ω ·m or more and 5.0×10 ⁻⁶ Ω·m or less is more preferable. When the volume resistivity of the first conductive linear body 21 is within the above range, when the first conductive linear body 21 and the second conductive linear body 71 are electrically connected, the first conductive linear body Heat generation in the shaped body 21 can be reduced, and heat generation in the second conductive linear body 71 can be increased.
The volume resistivity of the second conductive linear body 71 is preferably 1.0×10 ⁻⁹ Ω·m or more and 1.0×10 ⁻³ Ω·m or less, and preferably 1.0×10 ⁻⁸ Ω ·m or more and 1.0×10 ⁻⁴ Ω·m or less is more preferable. When the volume resistivity of the second conductive linear bodies 71 is within the above range, the surface resistance of the second pseudo-sheet structure 7 tends to decrease.
The measurement of the volume resistivity of the first conductive linear body 21 and the second conductive linear body 71 is as follows. Silver paste was applied to one end of the first conductive linear body 21 or the second conductive linear body 71 and a portion of 40 mm in length from the end, and the end and a portion of 40 mm in length from the end were coated. , and the resistance value of the first conductive linear body 21 or the second conductive linear body 71 is obtained. Then, the cross-sectional area (unit: m ² ) of the first conductive linear body 21 or the second conductive linear body 71 is multiplied by the above resistance value, and the obtained value is divided into the above measured length (0. 04m) to calculate the volume resistivity of the first conductive linear body 21 or the second conductive linear body 71 .

The cross-sectional shape of the first conductive linear body 21 and the second conductive linear body 71 is not particularly limited, and may be polygonal, flat, elliptical, circular, or the like. From the viewpoint of compatibility with the first resin layer 3 and the second resin layer 8, the cross-sectional shape of the first conductive linear body 21 and the second conductive linear body 71 is elliptical or circular. is preferred.

When the cross sections of the first conductive linear body 21 and the second conductive linear body 71 are circular, the thickness (diameter) D1 of the first conductive linear body 21 and the second conductive linear body The thickness (diameter) D2 (see FIGS. 2 and 3) of the body 71 is preferably 5 μm or more and 200 μm or less. From the viewpoint of suppressing an increase in sheet resistance and improving heat generation efficiency and dielectric breakdown resistance of the wiring sheet 100, the diameter D1 of the first conductive linear body 21 and the diameter D2 of the second conductive linear body 71 are It is more preferably 8 μm or more and 150 μm or less, and even more preferably 12 μm or more and 100 μm or less.
When the cross sections of the first conductive linear body 21 and the second conductive linear body 71 are elliptical, it is preferable that the major axis is in the same range as the diameter D1 and the diameter D2.

Diameter D1 of first conductive linear body 21 and diameter D2 of second conductive linear body 71 are determined by observing first conductive linear body 21 and second conductive linear body 71 using a digital microscope. Then, the diameters of the first conductive linear body 21 and the second conductive linear body 71 are measured at five randomly selected locations, and the average value is taken.

The interval L1 between the first conductive linear members 21 (see FIG. 2) and the interval L2 between the second conductive linear members 71 (see FIG. 3) are preferably 0.3 mm or more and 50 mm or less. It is more preferably 5 mm or more and 30 mm or less, and further preferably 0.8 mm or more and 20 mm or less.
If the distance between the first conductive linear bodies 21 or between the second conductive linear bodies 71 is within the above range, the conductive linear bodies are densely packed to some extent, so that the resistance of the pseudo-sheet structure can be lowered. It is possible to improve the function of the wiring sheet 100 such as maintenance.

The interval L1 between the first conductive linear members 21 and the interval L2 between the second conductive linear members 71 are determined by using a digital microscope, for example, by measuring the first conductive linear members 21 of the first pseudo-sheet structure 2. Observe and measure the distance between two adjacent first conductive linear bodies 21 .
The interval between two adjacent first conductive linear bodies 21 is the length along the direction in which the first conductive linear bodies 21 are arranged, and It is the length between opposing portions of the body 21 (see FIG. 2). The interval L1 is the average value of the intervals between all adjacent first conductive linear members 21 when the first conductive linear members 21 are arranged at uneven intervals. In addition, the interval L2 is the average value of the intervals between all adjacent second conductive linear members 71 when the second conductive linear members 71 are arranged at uneven intervals.

The first conductive linear body 21 and the second conductive linear body 71 are not particularly limited, but may be linear bodies containing metal wires (hereinafter also referred to as "metal wire linear bodies"). good. Metal wires have high thermal conductivity, high electrical conductivity, high handling properties, and versatility. The metal wire linear body can greatly reduce the resistance, and even if the diameter of the metal wire linear body is extremely small, the electric current required for heat generation of the wiring sheet 100 can be applied. Thereby, the first conductive linear body 21 and the second conductive linear body 71 can be made difficult to be visually recognized. That is, when metal wire linear bodies are used as the first conductive linear bodies 21 and the second conductive linear bodies 71, the resistance values of the first pseudo-sheet structure bodies 2 and the second pseudo-sheet structure bodies 7 are reduced. In addition, it becomes easy to improve the light transmittance. Moreover, the wiring sheet 100 is likely to generate heat quickly. Furthermore, as described above, it is easy to obtain a filamentous body having a small diameter.
As the first conductive linear body 21 and the second conductive linear body 71, in addition to the metal wire linear body, a linear body containing carbon nanotubes and a thread are coated with a conductive coating. A linear body is mentioned.

The metallic wire linear body may be a linear body made of one metal wire, or may be a linear body made by twisting a plurality of metal wires.
Metal wires include metals such as copper, aluminum, tungsten, iron, molybdenum, nickel, titanium, silver, and gold, or alloys containing two or more metals (for example, steel such as stainless steel and carbon steel, brass, phosphorus bronze, zirconium-copper alloys, beryllium-copper, iron-nickel, nichrome, nickel-titanium, kanthal, hastelloy, and rhenium-tungsten, etc.). In addition, the metal wire may be plated with tin, zinc, silver, nickel, chromium, nickel-chromium alloy, solder, or the like, and the surface thereof may be coated with a carbon material or the like, which will be described later. good too. In particular, a wire containing one or more metals selected from tungsten, molybdenum, and alloys containing these is preferable from the viewpoint of low volume resistivity.
Metal wires also include metal wires coated with carbon materials. When the metal wire is coated with a carbon material, the metallic luster is reduced, making it easier to make the presence of the metal wire inconspicuous. Metal corrosion is also suppressed when the metal wire is coated with a carbon material.
Examples of the carbon material that coats the metal wire include amorphous carbon (eg, carbon black, activated carbon, hard carbon, soft carbon, mesoporous carbon, carbon fiber, etc.), graphite, fullerene, graphene, carbon nanotubes, and the like.

A linear body containing carbon nanotubes is, for example, a carbon nanotube forest (a growing body in which a plurality of carbon nanotubes are grown on a substrate so as to be oriented in the vertical direction to the substrate, and is called an “array”). It can be obtained by drawing carbon nanotubes in a sheet form from the end of the carbon nanotube, bundling the drawn carbon nanotube sheet, and then twisting the bundle of carbon nanotubes. In such a production method, a ribbon-like carbon nanotube linear body is obtained when twisting is not applied during twisting, and a thread-like linear body is obtained when twisting is applied. A ribbon-shaped carbon nanotube linear body is a linear body that does not have a structure in which carbon nanotubes are twisted. Alternatively, a carbon nanotube linear body can be obtained by spinning a carbon nanotube dispersion. Production of carbon nanotube linear bodies by spinning can be performed, for example, by the method disclosed in US Patent Application Publication No. 2013/0251619 (Japanese Patent Application Laid-Open No. 2012-126635). From the viewpoint of obtaining a uniform diameter of the carbon nanotube linear body, it is desirable to use a filamentous carbon nanotube linear body. It is preferable to obtain a filamentous carbon nanotube linear body by The carbon nanotube linear body may be a linear body in which two or more carbon nanotube linear bodies are woven together. Also, the carbon nanotube linear body may be a linear body in which a carbon nanotube and another conductive material are combined (hereinafter also referred to as a "composite linear body").

As a composite linear body, for example, (1) a carbon nanotube linear body in which carbon nanotubes are pulled out in a sheet form from the ends of a carbon nanotube forest, the pulled out carbon nanotube sheets are bundled, and then the bundles of carbon nanotubes are twisted. In the process of obtaining a composite linear body in which a single metal or metal alloy is supported on the surface of a carbon nanotube forest, sheet or bundle, or twisted linear body by vapor deposition, ion plating, sputtering, wet plating, etc. , (2) a composite linear body in which a bundle of carbon nanotubes is twisted together with a linear body of a single metal or a linear body or a composite linear body of a metal alloy, (3) a linear body of a single metal or a metal alloy Composite linear bodies obtained by weaving linear bodies or composite linear bodies and carbon nanotube linear bodies or composite linear bodies, and the like. In the composite linear body of (2), when twisting the bundle of carbon nanotubes, a metal may be supported on the carbon nanotubes in the same manner as in the composite linear body of (1). The composite linear body of (3) is a composite linear body obtained by knitting two linear bodies. As long as linear bodies are included, three or more carbon nanotube linear bodies, linear bodies made of a single metal, linear bodies made of a metal alloy, or composite linear bodies may be woven together.
Examples of metals for the composite linear body include single metals such as gold, silver, copper, iron, aluminum, nickel, chromium, tin, and zinc, and alloys containing at least one of these single metals (copper-nickel-phosphorus). alloys, and copper-iron-phosphorus-zinc alloys, etc.).

The first conductive linear body 21 and the second conductive linear body 71 may be linear bodies in which a thread is coated with a conductive coating. Examples of the yarn include yarns spun from resins such as nylon and polyester. The yarns also include yarns of metal fibers, carbon fibers, ion conductive polymer fibers, and the like. Examples of conductive coatings include coatings of metals, conductive polymers, carbon materials, and the like. The conductive coating can be formed by plating, vapor deposition, or the like. A linear body in which a thread is coated with a conductive coating can improve the conductivity of the linear body while maintaining the flexibility of the thread. That is, it becomes easy to reduce the resistance of the first pseudo-seat structure 2 and the second pseudo-seat structure 7 .

The first conductive linear body 21 is preferably plated with gold from the viewpoint of suppressing the contact resistance between the first conductive linear body 21 and the first electrode 41 and the second electrode 42 . Since the first conductive linear body 21 is plated with gold, the resistance value of the first pseudo sheet structure 2 is stabilized, so that uneven heat generation can be easily suppressed. From the same point of view, second conductive linear body 71 is also preferably plated with gold.

(resin layer)
The first resin layer 3 and the second resin layer 8 are layers containing resin. The first pseudo-sheet structure 2 can be directly or indirectly supported by the first resin layer 3 . Moreover, the second pseudo sheet structure 7 can be directly or indirectly supported by the second resin layer 8 . The first resin layer 3 and the second resin layer 8 are preferably layers containing an adhesive. For example, when forming the first pseudo sheet structure 2 on the first resin layer 3 , the adhesive facilitates the attachment of the first conductive linear bodies 21 to the first resin layer 3 .

The first resin layer 3 and the second resin layer 8 may be layers made of a resin that can be dried or cured. As a result, sufficient hardness is imparted to the first resin layer 3 and the second resin layer 8 to protect the first pseudo-sheet structure 2 and the second pseudo-sheet structure 7, and the first resin layer 3 and the second The resin layer 8 also functions as a protective film. Moreover, the first resin layer 3 and the second resin layer 8 after curing or drying have impact resistance, and can suppress deformation of the wiring sheet 100 due to impact.

The first resin layer 3 and the second resin layer 8 are preferably curable with energy rays such as ultraviolet rays, visible energy rays, infrared rays, and electron beams, because they can be easily cured in a short time. The term "energy ray curing" includes heat curing by heating using energy rays.

The adhesive contained in the first resin layer 3 and the second resin layer 8 is a thermosetting adhesive that hardens with heat, a so-called heat seal type adhesive that adheres with heat, and an adhesive that develops sticking properties when wet. Also included are agents and the like. However, from the viewpoint of ease of application, it is preferable that the first resin layer 3 and the second resin layer 8 are energy ray-curable. Energy ray-curable resins include, for example, compounds having at least one polymerizable double bond in the molecule, and acrylate compounds having a (meth)acryloyl group are preferred.

Examples of the acrylate compounds include chain aliphatic skeleton-containing (meth)acrylates (trimethylolpropane tri(meth)acrylate, tetramethylolmethane tetra(meth)acrylate, pentaerythritol tri(meth)acrylate, pentaerythritol tetra( meth)acrylate, dipentaerythritol monohydroxypenta(meth)acrylate, dipentaerythritol hexa(meth)acrylate, 1,4-butylene glycol di(meth)acrylate, and 1,6-hexanediol di(meth)acrylate, etc.) , cycloaliphatic skeleton-containing (meth)acrylates (dicyclopentanyl di(meth)acrylate, dicyclopentadiene di(meth)acrylate, etc.), polyalkylene glycol (meth)acrylates (polyethylene glycol di(meth)acrylate, etc.) , oligoester (meth)acrylates, urethane (meth)acrylate oligomers, epoxy-modified (meth)acrylates, polyether (meth)acrylates other than the above polyalkylene glycol (meth)acrylates, and itaconic acid oligomers.

The energy ray-curable resin contained in the adhesive composition may be of one type or two or more types, and when two or more types are used, the combination and ratio thereof can be arbitrarily selected. Furthermore, it may be combined with a thermoplastic resin, which will be described later, and the combination and ratio can be arbitrarily selected.

The first resin layer 3 and the second resin layer 8 may be adhesive layers formed from an adhesive (pressure-sensitive adhesive). The adhesive for the adhesive layer is not particularly limited. Examples of adhesives include acrylic adhesives, urethane adhesives, rubber adhesives, polyester adhesives, silicone adhesives, and polyvinyl ether adhesives. Among these, the adhesive is preferably at least one selected from the group consisting of an acrylic adhesive, a urethane adhesive, and a rubber adhesive, and more preferably an acrylic adhesive.

Examples of acrylic pressure-sensitive adhesives include polymers containing structural units derived from alkyl (meth)acrylates having straight-chain alkyl groups or branched-chain alkyl groups (that is, polymers obtained by polymerizing at least alkyl (meth)acrylates ), an acrylic polymer containing structural units derived from a (meth)acrylate having a cyclic structure (that is, a polymer obtained by polymerizing at least a (meth)acrylate having a cyclic structure), and the like. Here, "(meth)acrylate" is used as a term indicating both "acrylate" and "methacrylate", and the same applies to other similar terms.

When the acrylic polymer is a copolymer, the form of copolymerization is not particularly limited. The acrylic copolymer may be block copolymer, random copolymer or graft copolymer.

When the acrylic polymer is a copolymer, the form of copolymerization is not particularly limited. The acrylic copolymer may be block copolymer, random copolymer or graft copolymer.

The acrylic copolymer may be crosslinked with a crosslinking agent. Examples of the cross-linking agent include known epoxy-based cross-linking agents, isocyanate-based cross-linking agents, aziridine-based cross-linking agents, and metal chelate-based cross-linking agents. When cross-linking an acrylic copolymer, a hydroxyl group, a carboxyl group, or the like that reacts with these cross-linking agents should be introduced into the acrylic copolymer as a functional group derived from the monomer component of the acrylic polymer. can be done.

When the first resin layer 3 and the second resin layer 8 are formed from an adhesive, the first resin layer 3 and the second resin layer 8 further contain the energy ray-curable resin described above in addition to the adhesive. You may have Further, when an acrylic pressure-sensitive adhesive is applied as the pressure-sensitive adhesive, the energy-ray-curable components include a functional group that reacts with a functional group derived from a monomer component in the acrylic copolymer, and an energy-ray-polymerizable functional group. A compound having both groups in one molecule may be used. The reaction between the functional group of the compound and the functional group derived from the monomer component in the acrylic copolymer enables the side chain of the acrylic copolymer to be cured by irradiation with energy rays. Even when the pressure-sensitive adhesive is not an acrylic pressure-sensitive adhesive, a component having an energy ray-polymerizable side chain may be used as a polymer component other than the acrylic polymer.

The second electrode 42 is electrically connected to one of the first conductive linear bodies 21 that is not electrically connected to the first electrode 41 . Therefore, the first conductive linear body 21 may be partly cut to shorten it, or an insulating tape may be pasted on one of both ends of the first conductive linear body 21 .
Next, a second sheet-like conductive member comprising a second base material 6, a second pseudo sheet structure 7, and a second resin layer 8 is prepared in the same manner as in the method for producing the first sheet-like conductive member described above. make.
