Abstract
A shell of a hermetically sealed package has a through hole and a circuit board is inserted and fixed hermetically into the through hole, and a can is fixed hermetically to the shell. The circuit board consists of a sealed part which is sealed hermetically by the hermetically sealed package, a fixed part to which the shell is fixed, and a projecting part which projects out from the hermetically sealed package. As the circuit pattern extends from the sealed part through the fixed part to the projecting part, it is not necessary to use terminal pins and instead a large number of external lead electrodes are taken out from the hermetically sealed package. An integrated-circuit chip or the like which is sealed by the hermetically sealed package can be shielded from electromagnetic influence by the metallic shell and the metallic can.
