Mode for carrying out the present invention is described in detail below.
1. structure
Fig. 1 is the schematic isometric for the structure that an embodiment is related to, and is shown the film substrate of covering structure body
Local excision after appearance.Fig. 2 is (ii)-(ii) line cross-sectional view in Fig. 1.
Structure 1 is made of tectosome 2 and film substrate 3.
Tectosome 2 has non-flat portion 21." non-flat portion " is the part for constituting the surface of tectosome 2, as long as
It is not included in the part in a plane, can be made of the combination of curved surface or multiple planes.In the present embodiment,
The case where non-flat portion 21 is made of curved surface is shown.
Film substrate 3 is disposed over the non-flat portion 21 of tectosome 2.
Two-sided in film substrate 3 is formed with metal fine drafting department (illustration omitted in Fig. 1 and Fig. 2).Referring to Fig. 3
It is described in detail for this point.
Fig. 3 is the figure being schematically illustrated to the film substrate 3 for constituting the structure 1 that an embodiment is related to.Fig. 3
In, the state (state of plane) before deformation is shown as film substrate 3.The film substrate 3 is in structure 1 along construction
The non-flat portion 21 of body 2 is deformed in nonplanar mode.Fig. 3 be equivalent to region A that the composition in Fig. 1 surrounded by dotted line (with
The non-flat portion 21 of tectosome 2 is corresponding) film substrate 3 enlarged drawing.
As shown in figure 3, being respectively formed with metal fine drafting department 4,4 (In on the surface of film substrate 3 31 and the back side 32
In the following description, sometimes by surface 31 and the back side 32 merge and referred to as two-sided 31,32.).
Metal fine drafting department 4 is made of the more metal fines 41 two-dimensionally configured on film substrate 3.In Fig. 3
Shown in solid, the metal fine 41 for constituting the metal fine drafting department 4 on the surface 31 of film substrate 3 is arranged along up and down direction,
And it is equipped with side by side at a prescribed interval along laterally multiple.As shown in phantom in Figure 3, the composition at the back side 32 of film substrate 3
The metal fine 41 of metal fine drafting department 4 is equipped with side by side at a prescribed interval along lateral setting, and along up and down direction
It is multiple.
Two-sided 31, the 32 each metal fine 41 for being respectively arranged on film substrate 3 includes non-linear shape.In present embodiment
In, metal fine 41 includes swash form element as non-linear shape.
Since metal fine 41 includes non-linear shape, so as to obtain following effect, it may be assumed that even if making film substrate 3
By the non-flat portion 21 along tectosome 2 in deforming in a manner of nonplanar, also can be avoided set on the two-sided of film substrate 3
The metal fine 41 for constituting metal fine drafting department 4 breaks.It estimates since the metal fine 41 for including non-linear shape plays bullet
Function as spring and stretch, thus play the effect is realized to tracing ability of deformation of film substrate 3 etc..
The metal fine 41 is including that the whole directions of length direction/width direction are played by the gold including non-linear shape
Belong to the retractility of 41 bring spring of filament.In addition, the retractility acts on prolonging direction, any one side in shrinkage direction
To.Therefore, the effect for being avoided that broken string can be obtained independent of the bending direction of the non-flat portion 21 of tectosome 2.Cause
This, is when being routed to metal fine 41, the bending direction of the non-flat portion 21 without centainly considering tectosome 2.For example,
Preferred pin forms metal fine respectively to the non-flat portion 21 of tectosome 2 and the planar section of tectosome 2 with identical patterns
41。
Especially, if making film substrate 3 by the non-flat portion 21 along tectosome 2 in deforming in a manner of nonplanar,
On the surface of film substrate 3 31 and the back side 32, bending state is different.For example, make film substrate 3 along the non-flat of convex
In the case that face part 21 deforms, surface 31 extends and the back side 32 is shunk.Alternatively, make film substrate 3 along concave non-flat
In the case that face part 21 deforms, surface 31 is shunk and the back side 32 extends.At this point, due to two-sided the 31 of film substrate 3,32 gold
Belong to filament 41 with retractility like a spring, so as to two-sided 31, the 32 simultaneous elongations in film substrate 3
Breaking line preventive effect is played with both sides are shunk.Therefore, tectosome 2 has in the case where non-flat portion 21 with convex
In the case where concave non-flat portion 21, or in non-flat portion 21 and concave non-flat face with above-mentioned convex
Divide in the case of 21, can be avoided the broken string of two-sided the 31 of film substrate 3,32 metal fine 41.
From the viewpoint of the retractility that can play such spring well, it is preferable that assign in metal fine 41
Non-linear shape is as swash form element shown in Fig. 3 or shape element shown in Fig. 7 etc. including relative to this
The length direction of metal fine 41 and turn round capable element repeatedly to the left and right.The torsion row for example can be round-trip multiple in the lateral direction,
Such as round-trip 2 times or more, 3 times or more, 5 times or more, even 10 times or more.
The whole shape of metal fine 41 can be bent in a manner of describing such as arc, as shown in figure 3, can be linearity
's.So-called linear to refer to: the center configuration of each amplitude formed along with the torsion row of metal fine 41 is in a straight line
On.The whole shape of metal fine mentioned here 41 is the state before film substrate 3 deforms, still, also can be from after deformation
The retracted position etc. of film substrate 3 confirms the state before deformation.
As described above, good electric conductivity is able to maintain and avoiding the broken string of metal fine 41.
In turn, since two-sided 31, the 32 each metal fine 41 for being respectively arranged on film substrate 3 includes non-linear shape, from
And the effect for reducing visual indisposed sense can also be obtained.This point is illustrated below.
Firstly, in the case where film substrate 3 is transparent, for example, if being equipped with image between tectosome 2 and film substrate 3
Display element then understands the pixel array Gan Wataru that have with image-displaying member and generates moir patterns in existing metal mesh opening,
Lead to visual indisposed sense.In contrast, since metal fine 41 includes non-linear shape, it can be avoided such Gan Wataru,
Moir patterns are not likely to produce, can reduce visual indisposed sense.It is not limited to the case where being equipped with pixel array, such as is had being equipped with
Also above-mentioned effect can be played in the case of the element of periodic patterns.
In addition, in the case where film substrate 3 is transparent, if two-sided 31,32 settings in film substrate 3 do not include non-linear
The metal mesh opening of shape, then between two-sided 31,32 metal mesh opening Fa Sheng Gan Wataru and generate moir patterns, cause visual indisposed
Sense.In contrast, since metal fine 41 includes non-linear shape, it can be avoided such Gan Wataru, be not likely to produce moir patterns, energy
Enough reduce visual indisposed sense.
Not only in the case where film substrate 3 is transparent, can also be played in the case where film substrate 3 can be had an X-rayed more than
Effect.
In addition, it is visual indisposed can also to obtain reduction in the case where film substrate 3 is opaque or cannot have an X-rayed
The effect of sense.For example, if any film is laminated on film substrate 3, when the film is formed with periodic patterns,
In existing metal mesh opening due to periodic patterns Gan Wataru and there may be moir patterns.In contrast, due to metal fine
41 include non-linear shape, can be avoided such Gan Wataru, is not likely to produce moir patterns, can reduce visual indisposed sense.Example
Such as, when using structure 1, even if the film etc. for being formed with periodic patterns is placed with (on film substrate 3) on structure 1
Article can also obtain the effect for being not likely to produce visual indisposed sense.
Such as electrostatic capacitance method can be used as in the film substrate 3 that two-sided 31,32 are formed with metal fine drafting department 4,4
Deng contact sensor etc. use.At this point, since X-direction position can be constituted by two-sided 31,32 metal fine drafting department 4,4
Set detecting electrode, one detecting electrode of Y-direction, therefore, with only in the case where single side is formed with metal fine drafting department compared with, can

The effect of positional shift.Thereby, it is possible to suitably play metal fine drafting department 4,4 bring functions (are with contact sensor
It is position detecting function if example).In addition, since film substrate 3 is monolayer constructions, thus in terms of cost also advantageously.Also
Have, since film substrate 3 is monolayer constructions, so as to relatively thinly form film substrate 3, the metal of two-sided 31,32 can be made
Distance between thread pattern portion 4,4 is close.The sensitive of the contact sensor for improving electrostatic capacitance method etc. can also be obtained as a result,
The effect of degree.
It is preferred that total metal fine density of two-sided 31, the 32 metal fine drafting departments 4,4 formed in film substrate 3
