A battery production method includes: preparing a battery element in which a positive electrode that includes a positive electrode current collector tab, and a negative electrode that includes a negative electrode current collector tab are stacked or wound through a separator; connecting a positive electrode pulled-out tab to the positive electrode current collector tab and connecting a negative electrode pulled-out tab to the negative electrode current collector tab; enclosing the battery element, positive electrode current collector tab and negative electrode current collector tab in a flexible exterior member, with the positive electrode pulled-out tab and negative electrode pulled-out tab being pulled out; forming a reference portion on the exterior member; and boring, in the positive electrode pulled-out tab and negative electrode pulled-out tab being pulled out of the exterior member, holes that are to be used for fixation, based on the reference portion after formation. |
