1. An energy storage apparatus, comprising:
an energy storage device; and
a spacer disposed:
adjacent to the energy storage device in a first direction; and
inward of the energy storage device in a second direction orthogonal to the first direction when viewed from the first direction,
wherein the spacer includes a concave-convex portion including at least one of a concave portion and a convex portion formed at an end portion in the second direction,
wherein the concave-convex portion is disposed separated from the energy storage device,
wherein the energy storage device includes a first energy storage device and a second energy storage device adjacent to each other,
wherein the spacer includes:
a main body portion having a plate shape, the main body portion facing the energy storage device only in a direction parallel to the first direction; and
a protruding portion protruding from the main body portion in the second direction,
wherein the protruding portion includes the concave-convex portion, and
wherein the protruding portion and the first energy storage device and the second energy storage device adjacent to each other are arranged without facing each other in the second direction.
