PURPOSE:To stabilize the quality and to improve the fixing force of circuit substrate fixing works, by providing plural claws for fixing a circuit substrate on a metallic plate for reinforcing the circuit substrate under a condition where the claws are united with the metallic plate in one body and making the width of the tip of each claw narrower than that of the base. CONSTITUTION:In an electronic circuit unit for electronic watch, which is composed of a semiconductor integrated circuit element, crystal oscillator, and metallic plate 2 which is used for reinforcing or ornamenting a circuit substrate 1 carrying a capacitor element, etc., and made of a high polymer material, the metallic plate 2 has plural clicks 3 formed at the outer peripheral part of the metallic plated under conditions where the claws 3 are united with the metallic plate 2 in one body. The clicks 3 are caused to stand from the metallic plate 2 at almost right angles and the width of the tip section 5 of each click 3 is made narrower than that of the base section 4. The clicks 3 are bent so as to embrace the circuit substrate 1 and the circuit substrate 1 is fixed to the metallic plate 2. |
