Energy storage apparatus, moving body, and energy storage system

An energy storage apparatus comprising:

• an energy storage device including a surface having a first end face from which an external terminal protrudes and a second end face on an opposite side from the first end face;
• and
• a retaining member that includes paired end portions disposed on opposite sides of the energy storage device in a second direction orthogonal to a first direction in which the external terminal protrudes and a coupling portion for coupling the paired end portions and that retains the energy storage device,
• wherein the coupling portion includes
• a main body portion facing the energy storage device in a third direction orthogonal to the first direction and the second direction,
• a first extending portion extending along the first end face from the main body portion, and
• an end extending portion extending along the end portion from the main body portion,
• a drain portion is provided to a position of the energy storage apparatus near the second end face, and
• the main body portion, the first extending portion, and the end extending portion are continuously connected to each other to thereby form first end corner portions of the coupling portion;
• the energy storage apparatus further comprising an insulating member for covering at least a face of the coupling portion facing the energy storage device,
• wherein the coupling portion has a second extending portion extending along the second end face from the main body portion,
• the insulating member has a convex part positioned astride the main body portion and the second extending portion between each of the end portions and the energy storage device adjacent to the end portion, and
• the drain portion is disposed on an outer side of the convex portion in the second direction.
