Provided is a resistor comprising a resisting plate (11) made of a metal plate and used as a resisting element, a radiating plate (15) of a metallic plate spaced from the resisting plate and arranged to cross the resisting plate, a mold resin element (19) involving the intersecting portion of the resisting plate and the radiating plate, terminal portions (11a) of the resisting plate, which are constituted by folding the two end portions of the resisting plate extending from the mold resin element, along the end faces and the bottom face of the mold resin element, and terminal portions (15a) of the radiating plate, which are constituted by folding the two end portions of the radiating plate extending from the mold resin element, along the end faces and the bottom face of the mold resin element. As a result, the metal plate resistor for the surface mounting of a resin seal is enabled to increase the power capacity drastically and to improve the reliability by hardly changing the size.
