Abstract: A circuit connection apparatus has a connector including a housing in which a connection terminal is contained, a positioning guide portion provided therein at an opposite side to an opening portion of the housing, and a press-fit terminal extended from the connection terminal. Moreover, the circuit connection apparatus has a heat sink that includes a guide receipt portion fitted with the positioning guide portion—and an opening to be penetrated by the press-fit terminal and to which the housing is fixed. Furthermore, the circuit connection apparatus has a circuit board that includes a board positioning guide portion and a through-hole to which the press-fit terminal is pressure-bonded and that is fixed to the heat sink. Because the press-fit terminal and the through-hole can accurately be positioned, it is made possible that the reliability is raised and a simple assembly process suppresses the production cost from rising.
