A method for manufacturing an electricity-storage module includes: preparing a stacked body and first sealing portions; processing an extension portion of one or more first sealing portions included in an outer edge portion in a stacking direction of the stacked body so that an extension portion length of the one or more of first sealing portions becomes shorter than a length of the extension portions of the first sealing portions which are not included in the outer edge portion; and forming a second sealing portion that is provided at the periphery of the first sealing portions when viewed from the stacking direction and covers at least parts of outer surfaces of the first sealing portions located at stacking ends of the stacked body in the stacking direction by injection molding in which a resin material is caused to circulate in a mold frame.
