Abstract: In an embodiment, an energy storage apparatus includes plural energy storage devices arranged in a first direction, and a frame arranged along the energy storage devices. Each of the energy storage devices has an outer surface facing in a second direction orthogonal to the first direction. The frame has a first portion extending in the first direction along the outer surface, and a second portion extending in the second direction toward a facing surface on which the energy storage apparatus is installed, from at least a part of the first portion.
