PROBLEM TO BE SOLVED: To provide a battery contact piece device restraining impedance between a battery contact piece and an electric circuit connecting part being a connecting mate. SOLUTION: This device has coil-spring shape battery contact pieces 43, 44 contactable with electrodes 53a, 54a of a battery to be installed through contact plates 45, 46. The contact pieces 43, 44 have leads 43b, 44b extending in spiral shapes from end turn parts 43e, 44e on a battery contact side toward the side of an electric circuit board 41 being the connecting mate, and tips of the leads 43b, 44b are soldered to a terminal of the circuit board 41. If the battery is loaded, the contact pieces 43, 44 are deformed in the direction of a coil axis to obtain appropriate contact pressure, and the leads 43b 44d are also elastically deformed similarly. According to this device, lengths of the leads 43b, 44b can be shortened, and impedance between the contact pieces 43, 44 and the circuit board 41 can be suppressed low. COPYRIGHT: (C)2005,JPO&NCIPI
