Reduced resistance, a robust connection structure and simplified connecting steps of an electricity storage device is attempted by inclusion of an electricity storage element (battery element 4) that is constituted by an electrode body in a positive side (current collector 120) and an electrode body in a negative side (current collector 140) that face each other while holding a separator (56, 58), a sealing member (sealing plate 18) that seals a case member accommodating the electricity storage element, at least one electrode protrusion (positive electrode part 12, negative electrode part 14) that is either of the electrode bodies, which is led out on an element end-face of the electricity storage element, at least one current collector plate (32, 34) that is connected to the electrode protrusion, and a terminal member (positive electrode terminal 28, negative electrode terminal 30, connecting plates 72, 74) that is installed in the sealing member, a lateral face of the terminal member being connected to that of any of the current collector plate. |
