Provided is a jumper or current detection resistor element having suppressed occurrence of connection defects resulting from the electromigration. The element (1) of the invention comprises a main body (11) consisting of a metal plate-shaped body, and terminal sections (12) provided at both ends of the main body; the terminal sections protruding from the main body, and both terminal sections provided with a mounting surface; and curved or cut surfaces (A, B, C, D, E) formed at periphery of the mounting surface. Both terminal sections are further provided with opposing surfaces at inside in direction of disposition of both terminal sections, and thickness of the opposing surfaces decreases from the mounting surface (13) to the main body (11).
