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 in a thickness direction of the battery, and a second housing portion that covers the interior space from a second side that is opposite to the first side in the thickness direction of the battery. The valve device is attached to the housing body and can make the interior space of the housing body be in communication with an external space. A joined edge portion is formed in the housing body as a result of the first housing portion and the second housing portion being fused along respective peripheral edge portions. The valve device is at least partially sandwiched between the first housing portion and the second housing portion in the joined edge portion. The first housing portion includes a bulge portion that is arranged on an inner side of an inner edge of the joined edge portion and bulges toward the first side with respect to the joined edge portion. An inner end of the valve device is located on an outer side of an outer edge of the bulge portion.

摘要： A battery includes a battery element, a housing body, and a valve device. The housing body houses the battery element. The valve device is in communication with the inside of the housing body. Heat-sealable resin layers face each other in a peripheral edge portion of the housing body. A joined edge portion in which the mutually facing heat-sealable resin layers are fused together is formed in the peripheral edge portion of the housing body. The valve device is configured to reduce an internal pressure of the housing body if the internal pressure is increased due to gas generated in the housing body. The valve device includes a first portion that is located on an outer side of an edge of the joined edge portion and a second portion that is sandwiched between the heat-sealable resin layers in the joined edge portion. Raised or recessed portions are formed in outer surfaces of a sandwiching portion of the joined edge portion where the second portion is sandwiched between the heat-sealable resin layers.
