1. An apparatus comprising:
a case body including a flat plate portion and a base portion projecting from the flat plate portion, the flat plate portion and the base portion of the case body together making up a single integral element, and the base portion comprising an upper surface;
a circuit board including a through-hole formed in a thickness direction, the base portion being inserted into the through-hole, wherein the circuit board is arranged onto the flat plate portion of the case body in a state in which the base portion is inserted into the through-hole; and
a battery secured on and held by the upper surface of the base portion,
wherein the base portion of the case body inserted into the through-hole in the circuit board penetrates through the through-hole and projects beyond the circuit board, and
wherein the base portion protrudes from the flat plate portion in the thickness direction by a base portion thickness greater than a corresponding thickness of the circuit board, such that the base portion provides clearance along the thickness direction between the circuit board and the battery.
