A joint for bonding parts together and preventing the overflow of an adhesive to opposite sides of a tip of an end edge part includes recesses that are formed in longitudinal directions on opposite sides of the tip of a circumferential wall part of a housing part, in the thickness directions. An abutting protruding part is protrusively provided in the longitudinal directions between the recesses. The abutting protruding part may be bonded with an adhesive, for example, to a circuit substrate. Excess portions of the adhesive that appear when bonding the abutting protruding part to the circuit substrate are stored in the recesses on opposite sides of the abutting protruding part, in the thickness directions without further overflow.
