Abstract: An insert bus bar plate includes a plate-shaped resin material and a plurality of metal bus bars that are embedded within the resin material by insert molding and have a terminal part exposed to a mounting surface that is one of principal faces of the resin material. The bus bars are formed, before the insert molding, as a bus bar assembly before molding the one ends different from the terminal part of which are coupled to each other by a carrier to be cut after the insert molding. The insert bus bar plate (a substrate main body) is formed by the insert molding performed by oppositely arranging two bus bar assemblies before molding of the same shape so that two terminal parts are positioned in between two carriers.

Abstract: To achieve efficient heat spreading and heat releasing by using a metal core of a circuit board, a terminal block includes an insulating block body and terminals. At least one of the terminals is provided with terminal portions for a connection with a circuit board. The terminal portions are inserted into respective through holes of the circuit board, the circuit board having a pattern circuit at a surface layer thereof and a conductive metal core at an intermediate portion in a thickness direction, so that heat of the metal core or of both the metal core and the pattern circuit is absorbed and transferred to the terminals. A bus-bar block includes an insulating block body and several parallel bus-bars with different lengths. Terminal portions at a tip end of the bus-bars are inserted, near heat-generating component on the circuit board, into the through holes of the circuit board.
