This invention provides an electrical junction box that can restrain a temperature from increasing in a casing. An electrical junction box 10 comprises a casing 11 made of a synthetic resin material, a circuit board 12 contained in the casing 11, semiconductor relays 32 mounted on the circuit board 12, a first bud bar 34, and a second bus bar 38. Both bud bars 34, 38 are insert-molded in the casing 11. The respective bus bars 34 and 38 include embedment sections 35A and 35B embedded in the casing 11, connecting sections 36A and 36B exposed from the casing 11 and thermally connected to the semiconductor relays 32.
