PURPOSE:To make thin the electronic watches having liquid crystal display device and to increase shock-proof, by loading a battery at the back cover of package to fix it so that a force due to the battery at shock can not be given to the circuit board. CONSTITUTION:A battery 207 is positioned with a battery guide member 210 consisting of an insulation substance fixed to the back cover 211 of a package, and the anode of the battery 207 is supported from the back cover 211 while being pressed with the anode terminal contact spring 209 fitted on the back cover 211 with spot welding and further, it is retained toward the back cover 211 with the cathode terminal contact spring 208 fixed removably to the battery guide 210, then the shock due to the mass of the battery 207 at shock can be absorbed with the contact spring 208 retaining the back cover 211 and the battery 207, allowing to avoid the effect on the circuit board 201. |
