| 1. An energy device comprising at least a plurality of sheet-shaped battery cells, in which a positive collector, a negative
collector, an electrode active material, and an electrolyte are laminated, and a plurality of substrates, the sheet-shaped
battery cell and the substrate being laminated alternately a plurality of times,
the energy device further comprising:
an internal wiring pattern that is formed on at least one substrate excluding a substrate constituting an outermost layer
of the energy device among the plurality of substrates, and that is not connected directly to any of the positive collector,
the negative collector, and the electrode active material;
a through electrode that electrically connects the internal wiring pattern to a surface of the energy device, and that is
not connected directly to any of the positive collector, the negative collector, and the electrode active material; and
a through optical device extending through the energy device.
