A storage module (M70SP) formed using a plurality of storage cells (70, 70A, 70B), wherein each storage cell (70, 70A, 70B) comprises: a storage unit that stores a charge; a polyhedral container that houses the storage unit and has a pair of two opposing surfaces (A,B) opposing in a front-rear direction and a left-right direction, respectively, and an upper surface; and a pair of electrode terminals that output and input the charge of the storage unit, characterized in that the electrode terminals (13, 13a, 13b) comprise: a positive electrode terminal that projects externally from the upper surface of the container and has a joint surface that is formed to be substantially coplanar with one of the two opposing surfaces of the container opposing in a left-right direction and joined to an electrode terminal of an adjacent storage cell (70, 70A, 70B) adjacent in a left-right direction; and a negative electrode terminal that projects externally from the upper surface of the container and has a joint surface that is formed to be substantially coplanar with the other of the two opposing surfaces of the container opposing in a left-right direction and joined to an electrode terminal of an adjacent storage cell (70, 70A, 70B) adjacent in a left-right direction, wherein the positive electrode terminal and the negative electrode terminal each have a joint surface (15c, 15d) that is formed to be substantially coplanar with a same one of the two opposing surfaces of the container opposing in a front-rear direction and joined to an electrode terminal (13a, 13b) of an adjacent storage cell (70, 70A, 70B), respectively, said adjacent cell being adjacent in a front-rear direction. a storage unit that stores a charge; a polyhedral container that houses the storage unit and has a pair of two opposing surfaces (A,B) opposing in a front-rear direction and a left-right direction, respectively, and an upper surface; and a pair of electrode terminals that output and input the charge of the storage unit, characterized in that the electrode terminals (13, 13a, 13b) comprise: a positive electrode terminal that projects externally from the upper surface of the container and has a joint surface that is formed to be substantially coplanar with one of the two opposing surfaces of the container opposing in a left-right direction and joined to an electrode terminal of an adjacent storage cell (70, 70A, 70B) adjacent in a left-right direction; and a negative electrode terminal that projects externally from the upper surface of the container and has a joint surface that is formed to be substantially coplanar with the other of the two opposing surfaces of the container opposing in a left-right direction and joined to an electrode terminal of an adjacent storage cell (70, 70A, 70B) adjacent in a left-right direction, wherein the positive electrode terminal and the negative electrode terminal each have a joint surface (15c, 15d) that is formed to be substantially coplanar with a same one of the two opposing surfaces of the container opposing in a front-rear direction and joined to an electrode terminal (13a, 13b) of an adjacent storage cell (70, 70A, 70B), respectively, said adjacent cell being adjacent in a front-rear direction. a positive electrode terminal that projects externally from the upper surface of the container and has a joint surface that is formed to be substantially coplanar with one of the two opposing surfaces of the container opposing in a left-right direction and joined to an electrode terminal of an adjacent storage cell (70, 70A, 70B) adjacent in a left-right direction; and a negative electrode terminal that projects externally from the upper surface of the container and has a joint surface that is formed to be substantially coplanar with the other of the two opposing surfaces of the container opposing in a left-right direction and joined to an electrode terminal of an adjacent storage cell (70, 70A, 70B) adjacent in a left-right direction, wherein the positive electrode terminal and the negative electrode terminal each have a joint surface (15c, 15d) that is formed to be substantially coplanar with a same one of the two opposing surfaces of the container opposing in a front-rear direction and joined to an electrode terminal (13a, 13b) of an adjacent storage cell (70, 70A, 70B), respectively, said adjacent cell being adjacent in a front-rear direction.
