STRETCHABLE CONDUCTOR SHEET, STRETCHABLE CONDUCTOR SHEET HAVING ADHESIVENESS, AND METHOD FOR FORMING WIRING LINE FORMED OF STRETCHABLE CONDUCTOR ON FABRIC

摘要

[Problem] To provide a stretchable conductor sheet which is useful as a material for electrical wiring lines and electrodes for wearable electronic devices, said material having excellent durability in terms of washing and durability in terms of perspiration.[Solution] A fabric provided with an electrode and an electrical wiring line, which are formed from a stretchable conductor sheet, is obtained by: providing a film having mold releasability with a first stretchable conductor layer which is formed from a paste material that uses carbon-based particles as a conductive filler, while using a flexible resin as a binder resin; subsequently forming a second stretchable conductor layer, while using metal-based particles as a conductive filler; laminating a hot melt adhesive layer thereon; superposing the resulting laminate on a fabric after removing unnecessary parts from the laminate by means of partial slits; and subjecting the resulting fabric to hot pressing. Since the carbon-based particles adsorb a contamination substance of the metal-based particles, oxidation degradation and sulfuration degradation of the metal-based particles is reduced, thereby improving the durability.
