Claim Text:
1. A current collector having a resin layer on at least one side of a conductive substrate, wherein: the resin layer has a thermoplastic resin dispersed in a thermosetting resin base material, the thermoplastic resin encapsuling at least a part of a conductive agent; the thermosetting resin base material is formed with a composition comprising a thermosetting resin and a hardening agent; the conductive agent is substantially dispersed only in the thermoplastic resin; a value given by (average thickness of the conductive agent)/(average thickness of the thermoplastic resin) is 0.5 to 3; the conductive agent is formulated so that a value of volume % given by (the conductive agent)/(the conductive agent+the thermoplastic resin) is 10% to 50%; and formulation ratio of the thermoplastic resin is 10% to 65 volume %, wherein the formulation ratio is given by the formula: (volume of the thermoplastic resin+volume of the conductive agent)/(volume of the thermoplastic resin+volume of the conductive agent+volume of the thermosetting resin+volume of the hardening agent).
