1. An energy storage apparatus, comprising:
a plurality of energy storage devices arranged in a first direction;
an adjacent member sandwiched between two adjacent energy storage devices among the plurality of energy storage devices;
a holding member that holds the plurality of energy storage devices and the adjacent member, the holding member including:
a pair of termination members arranged on both sides of the plurality of energy storage devices in the first direction; and
a pair of connecting members arranged on both sides of the plurality of energy storage devices in a second direction orthogonal to the first direction, and connecting the pair of termination members;
an insulating member interposed between the plurality of energy storage devices and one of the pair of connecting members;
a bus bar that electrically connects external terminals of the energy storage devices; and
a bus bar holding member that holds the bus bar, is arranged along the plurality of energy storage devices, and is made of resin,
wherein the bus bar holding member includes an elastic deformation portion and projects toward one of the adjacent member and the insulating member, and
wherein the elastic deformation portion contacts the one of the adjacent member and the insulating member, and contacts the bus bar holding member against an other of the adjacent member and the insulating member.
