PROBLEM TO BE SOLVED: To provide a battery bath which is zoned into a plurality of cell chambers by grid-like partition walls provided in an exterior wall of the bath wherein the partition walls and the external wall are favorably formed by injection mold; and to provide a molding method of effectively manufacturing the battery bath. SOLUTION: The battery bath is zoned into the plurality of cell chambers by the grid-like partition walls provided in the external wall 2 by injection mold. On the bottom of the battery bath 1, the bath has first injection gate traces 5 positioned at centers of the cell chambers 4 and second injection gate traces 6 positioned at the partition walls 3 zoning the endmost cell chambers and the cell chambers adjacent thereto. In the injection molding, first injection gates are provided at positions of cell chamber centers of the bath bottom; and second injection gates are provided at positions of the partition walls zoning the endmost cell chambers and the cell chambers adjacent thereto, whereby the battery bath is formed by injecting a resin from the first and second injection gates.
