In addition, about the exposed portions serve of silver-colored pattern 54b, be not limited to example shown in Figure 7, and can suitably change.Fig. 8 be the rigid substrates 5 that relates to of modified embodiment of the present embodiment ' on connecting portion 54 ' key diagram.In addition, in Fig. 8, to giving identical mark with the common formation of Fig. 7, and only carbon pattern 54c is applied oblique line.
In addition, the utility model is not limited to above-mentioned execution mode, can carry out after changing various and implements.In the above-described embodiment, about the illustrated size of accompanying drawing, shape etc., be not limited thereto, can in the scope of performance effect of the present utility model, suitably change.In addition, only otherwise the scope that breaks away from the purpose of this utility model just can suitably change and implement.
For example, in the connecting portion 54 of the rigid substrates 5 of above-mentioned execution mode, to being that the situation that the border is exposed the silver-colored pattern 54b of leading section side is illustrated with the straight line L that passes from the center of a plurality of through hole 54a.Yet the position on the border when silver-colored pattern 54b is exposed is not limited thereto, and can suitably changes.And the boundary line when silver-colored pattern 54b is exposed needn't be configured to the straight line shape, also can be rectilinear form or the curved shape with ladder difference.
And, in the connecting portion 54 of the rigid substrates 5 of above-mentioned execution mode, be illustrated for the situation with formation of stacked carbon pattern 54c on silver-colored pattern 54b.Yet the formation about connecting portion 54 is not limited thereto, and can suitably change.For example, also can use the stacked nickel pattern of copper pattern and then the stacked formation of golden pattern.But, under the situation aspect the cost when consider forming connecting portion 54, the such formation of preferred above-mentioned execution mode.
