In a heat radiator plate, a mounting bracket extending from a peripheral edge portion of the heat radiator plate, an auxiliary heat radiator plate portion extending along the mounting bracket and positioned between the mounting bracket 39 and a body through a gap and a radiant heat radiator portion formed on a top end of the auxiliary heat radiator plate portion and opposing to the body through the gap are provided. Heat generated by a circuit construction body is conducted from the heat radiator plate, the auxiliary heat radiator plate portion and the radiant heat radiator portion to the gap and radiated to the body through the gap. The heat radiation characteristics of the connector box are improved.
