ELECTRICAL STORAGE DEVICE

An energy storage apparatus (10) includes: an energy storage device (200); a substrate (500) in which a through hole (514) penetrating a main surface (510a) is formed; a through member (busbar (440)) that penetrates the through hole (514); and a lateral member (busbar frame (300)) disposed lateral to the substrate (500) and covering a side surface (510b) of the substrate (500). The lateral member includes an opening (321) through which at least one of two portions of the through member, the two portions sandwiching the through hole (514), is visually recognizable from the outside.
