Abstract
PURPOSE:To avoid short circuit by providing a groove on a fastening piece lying immediately below a wire connecting a circuit element and a lead and preventing the wire from coming into contact with the fastening piece even when it is deformed. CONSTITUTION:Circuit element 15 is fixed to fastening piece 10, and a plurality of leads 12 and circuit element 15 are connected by wire 16. Fastening piece 10 is provided with groove 14 on its part lying immediately below wire 16 so that wire 16 is prevented from coming into contact with fastening piece 10 even if wire 16 is deformed.
