Abstract

In an initial state, a battery is in the following state. A laminate has a thickness Tfrom a first electrode to a first electrode. A first position is spaced from the end portion of a separator on the first position side by a distance Lin a direction perpendicular to a thickness direction of the laminate. The end portion of a separator on the first position side protrudes toward the first position from the end portion of the second electrode on the first position side, by a distance G in the direction perpendicular to the thickness direction of the laminate. The laminate is designed such that, even if the laminate swells in the thickness direction of the laminate, the thickness of the laminate from the first electrode to the first electrode is smaller than 4×{(T/2)+L−(L−G)}.
