Patent ID: 7771869

Claim:
A secondary battery for an electronic appliance and configured to be accommodated in the electronic appliance, thereby providing electric power to the electronic appliance, the secondary battery comprising: a battery cell in which a positive electrode, a negative electrode and an electrolyte are accommodated in a pack, and a positive electrode terminal and a negative electrode terminal from the positive electrode and the negative electrode, respectively, extend from a same side face of the pack; a metallic battery can including an opening configured to receive the battery cell and which metallic battery can accommodates the battery cell therein such that the same side face, from which the positive electrode terminal and the negative electrode terminal extend, faces towards the opening side; and a lid comprising a synthetic resin in which a positive electrode terminal part and a negative electrode terminal part configured to be connected to electrodes of the electronic appliance and facing outwardly relative to the lid are provided and which lid plugs the opening of the battery can, the battery cell being accommodated in the battery can and the positive electrode terminal and the negative electrode terminal being curved between the same side face and the lid, the positive electrode terminal and the negative electrode terminal being folded over upon themselves such that, part of the positive electrode terminal directly overlaps itself between the lid and the same side face from which the positive electrode terminal extends, a first portion of the part of the positive electrode terminal that overlaps itself directly facing a second portion of the part of the positive electrode terminal across a first gap, and part of the negative electrode terminal directly overlaps itself between the lid and the same side face from which the negative electrode terminal extends, a first portion of the part of the negative electrode terminal that directly overlaps itself directly facing a second portion of the negative electrode terminal across a second gap.
