| abstract |
A secondary battery includes: a battery element including a positive electrode, a negative electrode, and an electrolyte; a accommodating member having an open end portion and accommodating the battery element; and a safety valve mechanism attached to the accommodating member so as to close the open end portion. The safety valve mechanism includes: a closing part, which closes the open end; and a connecting part, which is arranged between the battery element and the closing part, and has a connecting part that is electrically connected to the wound electrode body and the closing part, and that is physically connected to the closing part, respectively; A groove is provided in at least a part of the peripheral region of the connecting portion. |
