Abstract
An electricity storage device includes an electrode assembly, a case, a safety valve, and a cover member. The case accommodates the electrode assembly. The safety valve is arranged in the case and opens to discharge gas out of the case when an inner pressure of the case exceeds a release pressure. The cover member is arranged in the case opposing the safety valve and includes a flow passage for the gas.
