摘要： A battery includes a battery element, a housing body, and a valve device. The housing body is constituted by at least one laminate and includes an interior space in which the battery element is housed, a first housing portion that covers the interior space from a first side, and a second housing portion that covers the interior space from a second side. The valve device is attached to the housing body and can make interior space of housing body be in communication with an external space. A joined edge portion is formed in housing body as a result of the first and second housing portion being fused along respective peripheral edge portions. The valve device is sandwiched between the first and second housing portion in the joined edge portion, and an inner end of the valve device protrudes from an inner edge of joined edge portion toward the interior space.
