Description
Technical field
The present invention relates to the touch pad that constitutes at a face applying nesa coating of substrate with intermediate, be equipped with this touch pad with the touch pad of intermediate, can make and constitute in the mould of this touch pad with intermediate (in-mold) with metal pattern and make the touch pad intermediate manufacture method of this touch pad with intermediate.
Background technology
As this in-mold metal pattern, known have the Jap.P. spy to drive the interior metal pattern of mould that the 2004-152221 communique discloses.Metal pattern is equipped with movable metal pattern and fixing metal mould in this mould, constitutes and can utilize in-molded manufacturing touch pad substrate.Metal pattern engages two metal patterns under the state that duplicating film (film for internal mould) is inserted in the inner chamber in this mould, from the inner chamber injection resin material of cast gate to this state.Thus, make the touch pad molding substrate, and on the touch pad substrate, duplicate the ELD (nesa coating) of (applying) film for internal mould.
Under this situation, the touch pad substrate that utilizes metal pattern manufacturing in the above-mentioned mould is used for for example touch pad of resistance-type.Particularly, will put that pad (dot spacer) is clipped in the middle and the state relative with nesa coating is parallel down that a pair of touch pad substrate is set, the edge portion of two touch pad substrates of this state will be engaged, thereby make the touch pad of resistance-type.In the touch pad of this resistance-type, when touch operation is carried out with felt pen etc. in one surface of two touch pad substrates, be subjected to the position of touch operation to contact another touch pad substrate, make resistance change at this moment.Therefore, variation and definite touch location by detecting this resistance value can make this touch pad work as operating portion.
Summary of the invention
, there is following point in above-mentioned in-mold metal pattern.Promptly, in the above-mentioned resistive touch plate of the touch pad substrate that uses in-mold metal pattern moulding thus, the part that is subjected to touch operation is more recessed a little than other parts, so exist this recessed part to produce the problem that Newton ring makes the observability reduction of the inboard image that shows.In the case, it is such to consider to have Jap.P. spy for example to open the transparent composite that the 2005-18726 communique discloses, in that to form section on the nesa coating be triangle and highly be trickle ridge portion (jog of wire) about 0.1 μ m～10 μ m, produce trickle interference fringe (Newton ring), thereby do not influence the structure of image recognition.Yet the mode that general surface with the resinousness basilar memebrane with flexibility about thickness 50 μ m forms nesa coating is configured for in-molded film for internal mould.Therefore, even will in above-mentioned mould, the jog that section is leg-of-mutton trickle wire be set the forming surface (inner cavity surface) of metal pattern, and make above-mentioned transparent composite in-molded with trickle ridge portion with metal pattern in this mould, also, be difficult to the jog of hope is formed on the nesa coating of touch pad substrate because of basilar memebrane is the shape that padded coaming can't accurately describe to be formed on the jog of metal pattern in the mould.
The present invention is problem and finishing Given this, and its fundamental purpose is: provide a kind of and make touch pad that the touch pad that can seek to improve observability can improve observability with the intermediate manufacture method, in addition with the in-mold metal pattern of intermediate and touch pad with intermediate and touch pad.
In order to achieve the above object, in-mold metal pattern structure of the present invention is under the state that sandwiches the film for internal mould that forms nesa coating, can form and make the inner chamber of touch pad with the molding substrate of intermediate, by being injected resin, described inner chamber makes described molding substrate, make a face of this substrate described nesa coating of fitting simultaneously, thereby can make the in-mold metal pattern of touch pad with intermediate.Constitute therein in each inner cavity surface of described inner chamber and make on the inner cavity surface of a described face moulding, alternately parallel be provided with than the reference field of this inner cavity surface recessed and its bottom is formed or almost parallel parallel to this reference field the plane a plurality of wire recesses and protrude and its top formed a plurality of wire protuberances on the plane of or almost parallel parallel from this reference field to this reference field, form the jog that the inclined-plane separately by the face that connects this bottom and this top constitutes simultaneously.In addition, " inclined-plane " is as long as can obtain hereinafter the effect set forth (guarantee with inner cavity surface from bottom to the top of jog the desired height as height), and be certainly crooked.
In the case, form described jog and make the formation spacing of described each recess equate, and the formation spacing of described each protuberance equates.
Again, described jog structure can equate for the width separately along the described reference field on described bottom, described top and described inclined-plane.
Again, touch pad of the present invention with the intermediate manufacture method is, inner chamber to the in-mold metal pattern of the state that sandwiches the film for internal mould that forms nesa coating injects resin, make the molding substrate of touch pad with intermediate, make a face of this substrate this nesa coating of fitting simultaneously, thereby make the touch pad intermediate manufacture method of this touch pad with intermediate.Alternately parallel be provided with than reference field recessed and its bottom is formed or almost parallel parallel to this reference field the plane a plurality of wire recesses and protrude and its top formed a plurality of wire protuberances on the plane of or almost parallel parallel to this reference field from this reference field, simultaneously the jog that is made of the inclined-plane separately of the face that connects this bottom and this top is formed at the described inner chamber of the inner cavity surface that is shaped to described one side, described inner chamber is injected described resin, make described touch pad intermediate.
Again, the touch pad intermediate that the present invention is correlated with is the touch pad intermediate that is equipped with tabular substrate and utilizes the nesa coating of an in-molded face that is fitted in this substrate.On the described nesa coating of described substrate, alternately parallel be provided with than the reference field of this nesa coating recessed and its bottom is formed or almost parallel parallel to this reference field the plane a plurality of wire recesses and protrude and its top formed a plurality of wire protuberances on the plane of or almost parallel parallel from this reference field to this reference field, constitute jog by the inclined-plane separately that forms by the face that connects this bottom and this top.
Touch pad of the present invention, be equipped with described touch pad and form the touch lateral electrode of nesa coating, make described touch pad with constituting this touch pad intermediate and this touch lateral electrode relatively and with pad parallel setting that be clipped in the middle mutually between each described nesa coating of intermediate and described touch lateral electrode with intermediate with at a face of transparent sheet.
In-mold metal pattern of the present invention and touch pad are with in the intermediate manufacture method, to inner cavity surface by alternately parallel be provided with or almost parallel parallel to reference field formed respectively on bottom and top the recess of a plurality of wire that form respectively on plane with protuberance, form the inner chamber injection resin that jog that the inclined-plane separately by the face that is connected bottom and top constitutes constitutes, manufacturing touch pad intermediate simultaneously.So, according to this in-mold metal pattern and touch pad intermediate manufacture method, with not have plane earth that section is that leg-of-mutton jog is formed on the existing metal pattern of inner cavity surface different, even the basilar memebrane of rubber-like film for internal mould not exclusively is close to the whole surface of jog, also can in the bottom of recess and the top of protuberance basilar memebrane positively be close at least really.Therefore, the jog of the metal pattern height from the bottom to the height at top and nesa coating from bottom to the top of jog can be formed identical height.The result, according to this metal pattern and touch pad intermediate manufacture method, for fear of the generation of the interference fringe of bringing influence to image recognition and produce trickle interference fringe, can positively guarantee with from the bottom to the top as the desired height of height, thereby can shop drawings abundant apparent touch pad intermediate such as picture.
Again, according to in-mold metal pattern of the present invention, the jog that the formation spacing that forms each recess in inner cavity surface equates and the formation spacing of each protuberance equates, thus the formation spacing of each recess can be equated and jog that the formation spacing of each protuberance equates is formed on touch pad with on the nesa coating of intermediate.Therefore, can positively avoid really because their formation spacing difference causes that the recess of the jog that forms on the nesa coating and protuberance for example appear as arbitrarily appearance and bring the state of affairs of not harmony sense to the user.
Again, the jog that according to in-mold metal pattern of the present invention, form along the bottom, the width separately of the reference field on top and inclined-plane equates mutually in inner cavity surface, thus can form the jog that the width on bottom, top and inclined-plane equates mutually at nesa coating.Therefore, the distortion that can positively prevent image (displaying contents) that the inboard is shown is regarded as because like this undesirable of the figure of each width difference when causing changing because of the place.Again, above-mentioned each width is equated mutually, and with recess and protuberance respectively form spacing little, thereby can make jog very unshowy.Also since above-mentioned each width is equated and with recess and protuberance respectively form spacing little, can make the interval of the trickle interference fringe (light and shade) that the jog of nesa coating produced when touch pad carried out touch operation be reduced to the degree of (by closing in outline line) in the recessed outline line that occurs over just the touch pad that produces because of touch operation.Therefore, can be will this trickle interference fringe unshowy to the visual degree that almost can not see.
Again, according to touch pad according to the present invention intermediate and touch pad, form to have at nesa coating bottom and top are formed respectively to the recess of a plurality of wire on the parallel plane of reference field and protuberance and bottom being connected and the jog that constitutes of the inclined-plane separately of the face at top, produce trickle interference fringe for fear of the generation of the interference fringe of bringing influence to image recognition, can positively guarantee with from the bottom to the top as the desired height of height.So, with intermediate and touch pad, can under the state that is installed in the mounting object thing, make image that the inboard of touch pad shows etc. fully high-visible according to this touch pad.

In the case, as Fig. 6, shown in Figure 7, form on the inner cavity surface (the inner cavity surface 102d among Fig. 6, Fig. 7) of end face 11c (with reference to Fig. 1, Fig. 2) moulding that makes substrate 11 in each inner cavity surface of inner chamber 102a, be provided with and inject the cast gate 102c that uses by the resin from the flowable state of injection molding machine 104 of sprue 102b force feed in the inner chamber 102a.Particularly, with cast gate 102c be formed on be arranged in inner cavity surface 102d, along inner cavity surface (the inner cavity surface 102e of the two figure) side of the outside surface 11b moulding of the substrate 11 that removes film for internal mould 131 positions of living in that sandwich by main part 113 and main part 123 and along the position (as an example, the central portion of the length direction of inner cavity surface 102d) of the width of the film for internal mould 131 of the length direction (above-below direction of Fig. 4) of inner cavity surface 102d.Therefore, as shown in Figure 7, the pressure of the resin that injects in utilizing from cast gate 102c toward inner chamber 102a is pressed into the inner cavity surface 102f relative with inner cavity surface 102e (making the inner cavity surface of the inside surface 11a moulding of substrate 11) side with film for internal mould 131.
As shown in Figure 5, the ingredient of mobile side metal pattern 121 comprises basal part 122, main part 123, cushion block 124 and jet tray 125.Basal part 122 formation are tabular, and constitute the mobile side installation portion (not shown) that can be installed in injection molding machine 104.Main part 123 is fixed on basal part 122 by cushion block 124, forms inner chamber 102a with the main part 113 of fixation side metal pattern 111.
As shown in Figure 8, constitute the whole surface that makes the inner cavity surface 102f of inside surface 11a moulding in each inner cavity surface of inner chamber 102a and form the trickle recess 142 of wire with paper outside in this figure and the jog 141 of protuberance 143 with the inboard again.In the case, also can adopt the structure of the part formation jog 141 of inner cavity surface 102f.Again, as shown in the drawing, recess 142 is faces parallel to the inner cavity surface 102e of main part 113 under the state that engages of main part 113,123, it is recessed by the reference field 144 (with reference to this figure) of the inner cavity surface 102f at the center of the depth direction (short transverse) of jog 141 that it is formed ratio, and its bottom 142a is to reference field 144 parallel (or almost parallel).Again, as shown in the drawing, protuberance 143 is formed from reference field 144 protrusions, and its top 143a is to reference field 144 parallel (or almost parallel).Again, inclined-plane 145 is made of the face that connects bottom 142a and top 143a (being connected two 142a, 143a) respectively.
In the case, the structure of jog 141 is that height (degree of depth) L11 from bottom 142a to top 143a is more than 0.5 μ m in the scope below the 3 μ m.Also the structure of jog 141 being formed along width W separately 11, W12, the W13 of the reference field 144 on bottom 142a, top 143a and inclined-plane 145 is equal widths (as an example, in the scope below the above 0.4mm of 0.05mm).That is, jog 141 is formed to such an extent that the formation spacing of each recess 142 equates mutually and the formation spacing of each protuberance 143 equates mutually.
As shown in Figure 3, film for internal mould mobile device 103 is between fixation side metal pattern 111 and mobile side metal pattern 121, and in-molded each time (1 injection) makes film for internal mould 131 only move the length of regulation.Here, as shown in Figure 9, film for internal mould 131 comprises with the surface and has about the thickness 15 μ m～100 μ m of peel ply (not shown) and have flexibility and flexible resin (as an example, PET or PP (polypropylene)) forms basilar memebrane 132, constitutes nesa coating 12 that forms the film like about thickness 0.5 μ m～5 μ m on the surface of basilar memebrane 132 so that peel ply is clipped in the middle and the tack coat 134 that is formed on the surface of nesa coating 12 by tin-doped indium oxide (ITO) indium oxide of etc.ing.Moreover, as the material that constitutes nesa coating 12, be not limited to above-mentioned indium oxide, also can have the various materials of the transparency and electric conductivity with the zinc oxide fine particles of the tin oxide particulate of antimony doped tin oxide (ATO) and fluorine doped tin oxide (FTO) etc., Al-Doped ZnO (AZO) etc. and cadmium oxide etc.
As an example, the ingredient of injection molding machine 104 comprises (not shown) such as fixation side installation portion, mobile side installation portion, clamping, injecting mechanism and injection equipments.
Then, use manufacturing installation 101 (metal pattern 102) to make the operation of lower electrode 2a and touch pad 1 with the intermediate manufacture method according to touch pad of the present invention with reference to description of drawings.
At first, as shown in Figure 3, fixation side installation portion outside the figure of injection molding machine 104 and mobile side installation portion are installed the fixation side metal pattern 111 and the mobile side metal pattern 121 of metal pattern 102 respectively.Secondly, film for internal mould 131 is placed film for internal mould mobile device 103, make tack coat 134 relative, make 103 work of film for internal mould mobile device with the inner cavity surface 102e of fixation side metal pattern 111.At this moment, film for internal mould mobile device 103 makes film for internal mould 131 only move the length of regulation between the fixation side metal pattern 111 of metal pattern 102 and mobile side metal pattern 121.Then, make injection molding machine 104 work.At this moment; the clamping of injection molding machine 104 makes mobile side installation portion move toward the fixation side installation portion; as shown in Figure 7, the main part 113 of fixation side metal pattern 111 and the main part 123 of mobile side metal pattern 121 are bonded with each other with the state that sandwiches film for internal mould 131.
Then, the resin of the injecting mechanism force feed flow state of injection molding machine 104.At this moment, as shown in Figure 7, the resin of injection molding machine 104 force feeds injects in inner chamber 102a from cast gate 102c by sprue 102b.In the case, as shown in the drawing, this metal pattern 102 is provided with cast gate 102c in the inner cavity surface 102e side of removing film for internal mould 131 positions of living in that is positioned at inner cavity surface 102d and along the position of the width of the film for internal mould 131 of the length direction of inner cavity surface 102d.Therefore, the resin one side of injecting in from cast gate 102c toward inner chamber 102a is pressed into inner cavity surface 102f side with film for internal mould 131, one side is filled into inner chamber 102a, and the pressure of resin is close on the resin that is filled into inner chamber 102a the tack coat 134 that is clipped in the film for internal mould 131 that clips between resin and the inner cavity surface 102f.
In the case, as shown in Figure 8, in this metal pattern 102, owing to form jog 141, so be clipped in the shape (concaveconvex shape) of duplicating (describing) jog 141 on the film for internal mould 131 between the inner cavity surface 102f at inner cavity surface 102f.As a result, formation has the fine recesses 22 of wire and the jog 21 of protuberance 23 on the nesa coating 12 of film for internal mould 131.
Here, as indicated above, with basilar memebrane 132 with appropriate flexibility and flexible resin formation film for internal mould 131.Therefore, as shown in figure 11, there be not plane earth to form in the existing metal pattern 302 that section is triangular shaped jog 341 at inner cavity surface 302f, the elasticity that basilar memebrane 132 has causes and can not be close to basilar memebrane 132 fully at the recess 342 that constitutes jog 341 and the whole surface of protuberance 343, often produces the gap between bottom 342a and basilar memebrane 132.Promptly, basilar memebrane 132 is a padded coaming, thereby the shape of jog 341 accurately can not be duplicated (describing) to nesa coating 12, height (degree of depth) L12 from the bottom 22a of jog 21 to top 23a that forms is compared with height L11 from the bottom 342a of metal pattern 302 to top 343a, and the gap that hang down between bottom 342a and the basilar memebrane 132 is so many.As a result, though produce trickle interference fringe for fear of the generation of the interference fringe of bringing influence to image recognition, be difficult to guarantee with from bottom 22a to top 23a as the desired height (above-mentioned height L11) of height.
Relative therewith, in the metal pattern 102 of the present invention, the composition portion of jog 141 comprises bottom 142a is formed recess 142 to the parallel plane of reference field 144, top 143a is formed the protuberance 143 on the parallel plane of reference field 144 and the inclined-plane 145 that connects bottom 142a and top 143a.Therefore, even rubber-like basilar memebrane 132 not exclusively is close to the whole surface of jog 141, as shown in figure 10, also can positively be close at the top 143a and the basilar memebrane 132 of the bottom of recess 142 142a and protuberance 143 at least.As a result, the height L1 from the bottom 22a of jog 21 to top 23a of the height L11 from the bottom 142a of jog 141 to top 143a of metal pattern 102 and nesa coating 12 can be formed identical height.That is, by using metal pattern 102, the height L12 from bottom 22a to top 23a in the time of can making the existing metal pattern 302 of height L1 and use from bottom 22a to top 23a is more microscler to become jog 21.Thereby, produce trickle interference fringe for fear of the generation of the interference fringe of bringing influence to image recognition, can positively guarantee with from the bottom to the top as the desired height of height (height L11).
Then, after cool time through regulation, matched moulds by making injection molding machine 104 moves toward the direction that deviates from the fixation side installation portion, thereby removes engaging of fixation side metal pattern 111 and mobile side metal pattern 121, makes mobile side metal pattern 121 leave fixation side metal pattern 111.At this moment, moulding product (being substrate 11) that will the moulding by resin solidification separate from fixation side metal pattern 111 together with mobile side metal pattern 121.Then, the jet tray 125 that makes mobile side metal pattern 121 by the injection equipment that makes injection molding machine 104 makes the outer ejector pin of figure stretch out toward the place ahead of main part 123 toward main part 123 side shiftings, takes out the substrate 11 of moulding from mobile side metal pattern 121.In the case, because tack coat 134 is close to substrate 11 (adhesion), so film for internal mould 131 is taken out from mobile side metal pattern 121 together with substrate 11.
Then, peel the basilar memebrane 132 of film for internal mould 131 from substrate 11.In the case, because nesa coating 12 for to be attached to the state of the inside surface 11a of substrate 11 by tack coat 134, so peel basilar memebrane 132 from nesa coating 12 easily, makes nesa coating 12 be fitted in inside surface 11a.Thus, finish the manufacturing that comprises the substrate 11 and the lower electrode 2a of the nesa coating 12 of the inside surface 11a that is fitted in substrate 11.
Then, make upper electrode 2b.In the case, at first, will be coated on a face of the transparent sheet 31 that forms with for example PET as the tin-doped indium oxide (ITO) that nesa coating forms the material of usefulness, thereby form nesa coating 32 at a face of transparent sheet 31.Then, another face (touch face) of transparent sheet 31 is implemented dura mater processing and antireflection processing.Then, with transparent sheet 31 size (size roughly the same) cut-out in accordance with regulations that forms nesa coating 32 and finish above-mentioned processing with lower electrode 2a.Thus, finish the manufacturing of upper electrode 2b.
Then, two electrode 2a, the 2bs relative mutually with the nesa coating 32 of upper electrode 2b with the nesa coating 12 that makes lower electrode 2a sandwich a pad 3, and the outer peripheral edges portion with two electrode 2a, 2b of this state bonds with cementing agent etc.Then, terminal for connecting 4 is installed in the outer peripheral edges portion of two electrode 2a, 2b, and with lower electrode 2a in the inside surface 11a of substrate 11 go up the nesa coating 12 of fitting and the nesa coating 32 of upper electrode 2b is connected with terminal for connecting 4.Thus, finish touch pad 1.
In the case, as indicated above in this touch pad 1, by making lower electrode 2a in-molded with metal pattern 102, with from bottom 22a to top 23a as height, on nesa coating 12, form and have the jog 21 that produces the required height of trickle interference fringe.Therefore, can positively avoid the making a difference interference fringe of image recognition.So in this touch pad 1, image that can make the inboard that is presented at touch pad 1 under the state that is mounted to the mounting object thing etc. is fully high-visible.
Like this, this metal pattern 102 and touch pad are with in the intermediate manufacture method, inner cavity surface 102f is alternately parallel to be provided with bottom 142a and top 143a is formed recess 142 and protuberance 143 to a plurality of wire on the plane of reference field 144 parallel (or almost parallels) respectively, and the inclined-plane separately 145 that forms by the face that connects bottom 142a and top 143a constitutes jog 141, the inner chamber 102a that is made of this inner cavity surface 102f is injected resin, thereby make lower electrode 2a.So, according to this metal pattern 102 and touch pad intermediate manufacture method, with not have plane earth that section is that leg-of-mutton jog is formed on the existing metal pattern of inner cavity surface 302f different, even the basilar memebrane 132 of rubber-like film for internal mould 131 not exclusively is close to the whole surface of jog 141, also can positively at the top 143a of the bottom of recess 142 142a and protuberance 143 basilar memebrane 132 be close at least.Therefore, the height from the bottom 22a of jog 21 to top 23a of the height from the bottom 142a of jog 141 to top 143a of metal pattern 102 and nesa coating 12 can be formed identical height.The result, according to this metal pattern 102 and touch pad intermediate manufacture method, for fear of the generation of the interference fringe of bringing influence to image recognition and produce trickle interference fringe, can guarantee with from bottom 22a to top 23a as the desired height L1 of height, thereby can shop drawings abundant apparent lower electrode 2a such as picture.
Again, according to this metal pattern 102 and touch pad intermediate manufacture method, the formation spacing that jog 141 is constituted each recess 142 equates mutually and the formation spacing of each protuberance 143 equates mutually, by using this metal pattern 102 to make lower electrode 2a moulding, thereby can equate mutually in the formation spacing that lower electrode 2a form each recess 22 and jog 21 that the formation spacing of each protuberance 23 equates mutually.Therefore, can positively avoid because their formation spacing difference causes that recess 22 and protuberance 23 appear as for example random appearance and bring the state of affairs of not harmony sense to the user.
Again, according to this metal pattern 102 and Mo Nei intermediate manufacture method, width W separately 11, W12, W13 that jog 142 is constituted along the reference field 144 on bottom 142a, top 143a and inclined-plane 145 equate mutually, and by making lower electrode 2a moulding, thereby can form the width W 1 on bottom 22a, top 23a and inclined-plane 25, the jog 21 that W2, W3 equate mutually at nesa coating 12 with this metal pattern 102.Therefore, the distortion that can positively prevent image (displaying contents) that the inboard is shown is regarded as because like this undesirable of each width W 11, W12, W13 difference figure when causing changing because of the place.Again, above-mentioned each width W 11, W12, W13 are equated mutually, and with recess 142 and protuberance 143 respectively form spacing little, thereby can make the jog 21 that forms on the nesa coating 12 of lower electrode 2a very unshowy.Also since each width W 11, W12,13 are equated mutually and with recess 142 and protuberance 143 respectively form spacing little, can make the interval of the trickle interference fringe (light and shade) that the jog of nesa coating 12 produced when touch pad 1 carried out touch operation be reduced to the degree of (by closing in outline line) in the recessed outline line that occurs over just the touch pad 1 that produces because of touch operation.Therefore, can be will this trickle interference fringe unshowy to the visual degree that almost can not see.
Again, lower electrode 2a according to this touch pad 1 and touch pad 1 usefulness, form to have at nesa coating 12 bottom 22a and top 23a are formed respectively the recess 22 of a plurality of wire on the parallel plane of reference field 24 and protuberance 23 and the inclined-plane separately 23 of the face of 22a and top 23a constitutes bottom being connected jog 21, thereby produce trickle interference fringe for fear of the generation of the interference fringe of bringing influence to image recognition, can positively guarantee with from bottom 22a to top 23a as the desired height L1 of height.So the lower electrode 2a that uses according to this touch pad 1 and touch pad can be under the state that is mounted to the mounting object thing, make image that the inboard of touch pad 1 shows etc. fully high-visible.
Moreover, the invention is not restricted to above-mentioned composition.For example, above record and narrate the example that substrate 11 is formed rectangular plate shape, but also substrate 1 can have been formed be not limited thereto tabular arbitrarily.Can set arbitrarily the length of the wide W11～W13 on bottom 142a, the top 143a of the length of wide W1～W3 on bottom 22a, the top 23a of nesa coating 12 and inclined-plane 25 and metal pattern 102 and inclined-plane 145 again.Again, though above recorded and narrated on the nesa coating 12 jog 21 that forms from the height L11 from bottom 142a to top 143a of the jog 141 that forms to the inner cavity surface 102f of the height L1 of top 23a and metal pattern 102 of bottom 22a be the example in the following scope of 3 μ m more than the 0.5 μ m, can set arbitrarily that these are highly.Again, though above recorded and narrated width W separately 1 along bottom 22a, top 23a and inclined-plane 25, W2, W3 and be the example that constitutes in the following scope of the above 0.4mm of 0.05mm, can set arbitrarily the size of these width along width W separately 11, W12, the W13 of the reference field 144 on bottom 142a, top 143a and inclined-plane 145 along reference field 24.And, though above recorded and narrated jog 21 is configured so that example that width W 1, W2, W3 equate and jog 141 is configured so that the example that width W 11, W12, W13 equate, also can adopt to make the different structure of each width W 1, W2, W3 and make each width W 11, structure that W12, W13 are different.
