PROBLEM TO BE SOLVED: To provide a photosensitive conductive ink which is excellent in photosensitivity and developability, and can form a conductive layer excellent in electroconductivity, adhesion, wet heat resistance and the like. A photosensitive conductive ink containing a photosensitive resin (A), conductive particles (B) and a photopolymerization initiator (C), wherein the photosensitive resin (A) is an epoxy compound (a). A compound having a polybasic acid anhydride (d), an epoxy group or an oxetane group, and an ethylenically unsaturated group (c) having a hydroxyl group in the side chain formed by reacting a phenol compound (b) with f) and a polybasic acid anhydride (g), which is a photosensitive resin (A-1) or (A-2) having a carboxyl group and an ethylenically unsaturated group in the side chain. A photosensitive conductive ink characterized by [Selection figure] None |
