A sheet-shaped energy device includes at least sheet-shaped battery cells, in each of which a positive collector, a negative collector, a positive active material, and an electrolyte are laminated, and a plurality of substrates in a thickness direction. An internal wiring pattern and/or an optical function part are formed on at least one substrate excluding a substrate constituting an outermost layer of the energy device among the plurality of substrates. Because of this, a constraint on the arrangement of various kinds of components used simultaneously with the sheet-shaped energy device and lengthy wiring can be reduced in electronic equipment.
