  • Patent number: 10588569
    Abstract: A conductive fabric including a fabric and a wiring provided on the fabric, wherein the wiring has a first insulating layer formed on the fabric, a conductive layer provided on the first insulating layer, and a second insulating layer provided on the conductive layer, and wherein in a stretching test in which the conductive fabric is stretched by a stretching rate of 10% in a stepwise manner up to a stretching rate of 100% in a longitudinal direction of the wiring, a resistance change ratio when stretched at a stretching rate of 100% is 100-fold or less, the resistance change ratio when stretched at a stretching rate of 100% being represented by an equation: R100/R0 (fold), where R0 is a resistance value at a stretching rate of 0% and R100 is a resistance value when stretched at a stretching rate of 100%. The conductive fabric is capable of maintaining high electrical conductivity even upon being stretched.
