Summary:PROBLEM TO BE SOLVED: To suppress scattering in all directions of an electrolyte ejected due to a rise in internal pressure of each of a plurality of cells, in a battery module in which the plurality of cells and holders are alternately laminated in parallel.SOLUTION: A cell 10 is provided with an explosion-proof valve 13 to be opened in response to a rise in internal pressure in the cell 10. A holder 20 is integrally provided with a holder tongue piece 33 covering the explosion-proof valve 13. When the explosion-proof valve 13 is opened, scattering of an electrolyte in all directions is suppressed by the holder tongue piece 33.
