Abstract
In a battery in which a metallic battery case for accommodating electricity-generating elements also serves as an electrode, a visible-light or near-infrared-light curing resin is used for providing a coating to insulate an end face and a peripheral edge portion of an opening portion of the battery case or a gap between a positive electrode and a negative electrode. The visible-light or near-infrared-light curing resin excels in a depth-curing characteristic as compared with a conventional ultraviolet curing resin, and cures well even up to a portion such as an insulating seal of a battery where a light-receiving port is light and the light is difficult to reach. Hence, the visible-light or near-infrared-light curing resin is prevented from becoming peeled off and provides a reliable insulting characteristic.
