A multi-layer bus bar unit capable of being easily made into a product coping with a demand for different specifications, reducing production costs including initial costs such as a cost for manufacturing a die, and ensuring long-term reliability is provided. Coating films 11 and 21 are deposited on a first bus bar 10 and a second bus bar 20, each formed from a metal flat plate, by an electrodeposition coating process with a polyamidimide electrodeposition coating material. The coating film 11 of the first bus bar 10 is subjected to a heating treatment to form a completely-cured resin covering layer 12, and the coating film 21 of the second bus bar 20 is subjected to a heating treatment to form a semi-cured resin covering layer 22. The first bus bar 10 and the second bus bar 20 are overlapped with each other and then subjected to a pressure and heating treatment so that the semi-cured resin covering layer 22 is completely cured. In this manner, a multi-layer bus bar unit 1 having a two-layer structure in which the first bus bar 10 and the second bus bar 20 adhere to each other by the resin covering layers 12 and 22 is formed.
