Abstract

L'objet de la présente invention est de fournir un tissu conducteur qui peut supprimer la détérioration d'un conducteur dans la position de connexion d'une borne de connexion à un dispositif externe. L'objet est également de fournir un tissu conducteur présentant une structure de connexion à des dispositifs externes qui fournit une résistance suffisante sans amoindrir la texture du tissu, et un procédé de fabrication du tissu conducteur. Ce tissu conducteur (10) comporte une partie adhérée (Z) conductrice stratifiée et fixée à celui-ci, et est pourvu : d'une partie conductrice (12) qui est constituée d'une structure en fibres conductrices et qui est connectée électriquement à la partie adhérée (Z) ; et d'un adhésif de résine (15) qui remplit au moins une partie de la région dans laquelle est disposée la partie conductrice (12), et relie et fixe la partie adhérée (Z) à la partie conductrice (12) dans un état de contact direct.
