The casing and the lid are respectively provided with narrow grooves communicating with the recessed portion. The casing and the lid are welded together by a ultrasonic welding method at their peripheral edges with the exception of the narrow grooves and portions outside thereof, thereby forming a very narrow gap between the casing and the lid.
