Abstract: A battery pack includes: cells, and electrode tabs including a positive electrode tab and a negative electrode tab which are connected with the power generation element, and which are provided to protrude from end portions of the outer member; frame members each including a front surface and a back surface on which the pair of the cells are mounted; conductive members each of which is disposed on the frame member, and each of which electrically connects the electrode tabs of the pair of the cells; and bus bars each of which electrically connects the conductive members disposed on the frame members of the plurality of the stacked frame members, and which are adjacent in a stacking direction.

Abstract: A battery module has at least one individual cell and a housing. The individual cell has a power generating element with positive and negative electrodes stacked with a separator therebetween and sealed by a cladding material. The housing has a pair of cases that sandwiches the cell from opposite sides and a plate shaped reinforcing member joined to and reinforcing one of the cases. One of the cases has a bulging portion, a first extension portion, an inclined portion and a second extension portion. The bulging portion protrudes toward and presses the cell. The first extension portion extends transversely from the bulging portion with respect to the stacking direction. The inclined portion extends from the first extension portion while sloping toward the cell. The second extension portion extends transversely from the inclined portion with respect to the stacking direction. The second extension portion is joined to the reinforcing member.
