Abstract: An electricity storage unit of the present disclosure includes: electricity storage device; holder for holding this electricity storage device; bottomed tubular case for housing electricity storage device and holder; and cover for covering opening of case. At least a part of cover is inserted into case. With this configuration, since a surface on which a joint between cover and case is formed can be disposed on an opening side of case, it is possible to suppress intrusion of a foreign substance, such as a water droplet.
