Abstract: A material 2 is used as the fabric of a shirt, and formed by knitting a blended yarn of polyester and urethane. The material 2 is flattened by a calendering process. A conductive ink is printed on an insulating layer serving as an underlayer to form wiring layers L1 to L10. The conductive ink contains carbon nanotubes. Consequently, wiring layers that ensure a sufficient conductivity can be obtained.

Abstract: [Problem to be Solved] To provide an electrode sheet which has ensured electroconductivity of a wiring layer. [Means for Solving Problems] Polyester polyurethane blended yarns as fibers of a shirt are woven to constitute a cloth (2). This cloth (2) is calendered for flattening. An insulating layer is provided as a substrate and an electroconductive ink is printed thereon to form wiring layers (L1 to L10). The electroconductive ink contains carbon nanotubes. According to the above constitution, wiring layers having satisfactory electroconductive can be provided.
