Abstract: An electrode group formed by winding a positive electrode plate and a negative electrode plate with a separator interposed therebetween is housed in a battery case, and a sealing plate seals an opening of the battery case. The sealing plate includes an upper metal plate, a valve, and a lower metal plate that are stacked, an insulating plate is placed on a portion of the electrode group near the opening of the battery case, one of the positive electrode plate or the negative electrode plate of the electrode group is connected to the lower metal plate through a lead, the lower metal plate and the insulating plate have a first opening and a second opening, respectively, and a ratio of S2 is within the range of 1.8-3.3, where S1 represents an area of the first opening, and S2 represents an area of the second opening.

Abstract: A secondary battery includes an electrode body that includes a positive electrode plate and a negative electrode plate an outer body that houses the electrode body; a sealing plate that is made of metal and seals an opening of the outer body; and a positive electrode terminal that is electrically connected to the positive electrode plate. At least part of the positive electrode terminal is disposed on the battery outer side with respect to the sealing plate. An external insulating member made of resin is disposed between the sealing plate and the positive electrode terminal. The conduction path between the positive electrode plate and the positive electrode terminal is provided with a current interrupting mechanism. An electrically insulating, heat resistant layer is disposed between the positive electrode terminal and the sealing plate.
