摘要： A stretchable contractible wiring sheet includes: stretchable contractible first elastomer sheet; stretchable contractible second elastomer sheet facing and bonded on the first elastomer sheet, and lead that has a transverse section having any cross-sectional shape selected from circular shape, elliptical shape, and track shape, and is plastically deformed in wavy shape periodically curving along longer direction, the lead being interposed between the first elastomer sheet and the second elastomer sheet in a manner that height direction of waves in wavy shape is along in-plane direction of facing surfaces of the first elastomer sheet and second elastomer sheet. The wiring sheet that can be produced easily at low costs, has high flexibility and durability, and undergoes small resistance value change along with stretching and contracting, and stretchable contractible touch sensor sheet.

摘要： [Problem] To provide a high-stretchability/contractibility stretchable contractible wiring sheet that can be produced easily at low costs, has high flexibility, high durability, and high conformity to external force, and undergoes small resistance value change along with stretching and contracting and a producing method and apparatus for the same, and a stretchable contractible touch sensor sheet.[Solution] A stretchable contractible wiring sheet of the present invention includes: a stretchable contractible first elastomer sheet 1a; a stretchable contractible second elastomer sheet 1b facing and bonded on the first elastomer sheet 1a; and a lead 2 interposed between the first elastomer sheet 1a and the second elastomer sheet 1b in a state of having a wavy shape periodically curving in-plane in facing surfaces of the first elastomer sheet 1a and the second elastomer sheet 1b and being biased in a direction to restore to a rod-like shape from the wavy shape during unloading.
