Abstract
(EN)
[Problem] The first problem to be addressed by the present invention is to provide a conductive member which has excellent impact resistance and with which the disconnection of thin metal wires is inhibited when the conductive member is used in a process where there is exposure to a high-temperature and/or high-pressure environment. The second problem to be addressed by the present invention is to provide a touch panel sensor and a touch panel that use the conductive member. The third problem to be addressed by the present invention is to provide a method for manufacturing a molded body that uses the conductive member. [Solution] A conductive member includes: a base material; an intermediate layer disposed on at least one surface of the base material; a patterned layer to be plated that is disposed in a mesh shape on the intermediate layer and has a functional group interacting with a plating catalyst or a precursor thereof; a mesh-shaped metal layer that is disposed on the patterned layer to be plated and is formed by a plurality of thin metal wires intersecting; and a protective layer disposed on the metal layer. When the elastic modulus of the base material at 25°C is defined as a, and the elastic modulus of the intermediate layer at 25°C is defined as b, formula A is satisfied. Formula A: 0.010≤b/a≤0.500. The surface area of the metal layer is 0.2-60%, and the elastic modulus of the protective layer at 25°C is 0.10-5.00 GPa.

La présente invention ‌a‌ ‌également pour‌ ‌objet‌ de‌ fournir un capteur d'écran tactile et un écran tactile qui utilisent l'élément conducteur. La présente invention ‌a‌ ‌également pour‌ ‌objet‌ de‌ fournir un procédé de fabrication d'un corps moulé qui utilise l'élément conducteur. À cet effet, l’invention porte sur un élément conducteur qui comprend : un matériau de base ; une couche intermédiaire disposée sur au moins une surface du matériau de base ; une couche à motifs devant être plaquée qui est disposée en forme de maille sur la couche intermédiaire et qui a un groupe fonctionnel interagissant avec un catalyseur de placage ou un précurseur de celui-ci ; une couche métallique en forme de maille qui est disposée sur la couche à motifs devant être plaquée et qui est formée par une pluralité de fils métalliques minces se croisant ; et une couche de protection disposée sur la couche métallique. Lorsque le module élastique du matériau de base à 25 °C est défini comme a, et le module élastique de la couche intermédiaire à 25 °C est défini comme b, la formule A est satisfaite. Formule A : 0,010 ≤ b/a ≤ 0,500. La surface de la couche métallique est de 0,2 à 60 %, et le module élastique de la couche protectrice à 25 °C est de 0,10 à 5,00 GPa.
