ABSTRACT:
A casing of an electronic key communicating apparatus is formed by sealing with epoxy resin a printed circuit board, a front surface of which a circuit component and end portions of each terminal are mounted on. A rear surface of the circuit board is used as a part of an outer surface of the casing. The circuit board includes a recess line portion to surround a button battery. The terminals are mounted on the printed circuit to cross the recess line portion. This structure allows a slide type mold to be used, decreasing the thickness of the casing and enhancing productivity.
