PROBLEM TO BE SOLVED: To realize small-sizing of electric connection between a battery receiver spring and a circuit board. SOLUTION: A timepiece has a timepiece train wheel between a cope plate 1 and a train wheel receiver 2 and comprises a circuit board 7 consisting of insulation members arranged below the train wheel receiver 2, a battery 12 arranged on the upper surface of the train wheel receiver 2 by way of an insulation sheet 11, and a spring member (battery receiver spring plate 13) arranged partly at the lower surface of the circuit board 7 and at the lower surface of the train wheel receiver 2. By pushing up a part of the circuit board 7 with the energized force of the battery receiver spring plate 13, and elastically pressing a minus pattern 14 formed on the upper surface of the circuit board 7 to the cathode 12a of the battery 12 through a notch 2a formed in the train wheel receiver 1, the battery 12 and the circuit board 7 are electrically connected to supply the circuit board 7 with power of the battery 12. This results in higher reliability in electrical connection and elimination of connection space and possibility of reduction of size. COPYRIGHT: (C)2004,JPO
