摘要： A member for electric conduction, comprising a metal member and a resin member that is joined to at least a part of a surface of the metal member, the metal member having a roughness index, which is obtained by dividing a true surface area (m 2 ) measured by a krypton adsorption method by a geometric surface area (m 2 ), of 4.0 or more.
