摘要:
A sheet-shaped stretchable structure including stretchable resin sheets laminated together is provided. A conductive layer may be disposed at least at one of several positions. For example, the conductive layer may be disposed between any two adjacent ones of the laminated stretchable resin sheets. The conductive layer may be disposed on a top surface of an uppermost one of the laminated stretchable resin sheets. Further, the conductive layer may be disposed on a bottom surface of a lowermost one of the laminated stretchable resin sheets, and a via hole.

The present invention relates to an electrically conductive film characterized by being able to undergo elastic deformation, having little residual strain rate and exhibiting stress relaxation properties. More specifically, the present invention relates to an electrically conductive film wherein the stress relaxation rate (R) and the residual strain rate (alpha), as measured in a prescribed extension-restoration test, are as follows: 20%≦R≦95% and 0%≦α≦3%.

Provided is a structural member for electronic devices which uses a material that is flexible and has excellent restoration properties after extension and stress relaxation properties. The structural member for electronic devices has the following properties A and B: (Property A) In a case where predetermined deformation is applied, stress that applies the deformation is relaxed (reduced) with time: and (Property B) In a case where the stress that applies deformation is 0, the deformation rarely remains while a resin composition is recovered. That is, when stress is 0, residual strain substantially becomes 0 (specifically 3% or lower).

A conductive film includes a film substrate and a conductive layer formed on at least one surface of the film substrate. The film substrate and the conductive film have elongation of 10% or more. Ten-point average roughness Rz of the surface of the film substrate on at least a conductive layer side is 0.05 to 0.5 μm, and an average interval Sm of unevenness is 0.1 to 1 μm.
