Abstract: A bus bar holding structure includes a bus bar, an insulating resin-made wire distribution body holding the bus bar. The bus bar electrically connects together an adjacent terminals of a plurality of unit cells each having positive pole and negative pole electrode terminals. The bus bar includes a plate-shaped main body and a wire connecting part extended from the plate-shaped main body and connected to an end of a wire. The plate-shaped main body includes a fold-back part and a plurality of plate parts separated from each other at the fold-back part and folded back at the fold-back part so as to be superimposed with each other. The plate-shaped main body and the wire connecting part are formed integrally.

Abstract: A busbar includes a plate-shaped body section and a wire connection section extended from the body section. The body section includes a first plate section, a second plate section, and a folding-back section connecting the first plate section and the second plate section. The first plate section and the second plate section are stacked mutually by folding-back the folding-back section. The first plate section has an outer shape that is positioned to a busbar accommodation section of a wire routing member made of insulation resin. A maximum width dimension of the second plate section in a direction parallel to the folding-back section is smaller than that of the first plate section in the direction parallel to the folding-back section.

Abstract: A coil unit includes a ferrite including a coil base in a form of a frame, on which a coil is arranged, and formed from a plurality of divided ferrites. The plurality of divided ferrites include a first divided ferrite and a second divided ferrite which form a corner piece and a third divided ferrite and a fourth divided ferrite which form a side piece.
