Abstract
A module comprises a metallic terminal pins for connection and a circuit board with electronic components mounted thereon, a circuit board connecting side of the connector. The electronic components and the circuit board with the electronic components mounted thereon are encapsulated with the same resin. A metallic base is united to the module to obtain an electric conduction between the metallic base and the circuit board.
