Abstract

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.
