Abstract: Provided are a dissimilar metal welded body and a method of manufacturing the same, capable of preventing galvanic corrosion in a connection portion between dissimilar metals in the dissimilar metal welded body and of sufficient insulation coating being applied even when the insulation coating is applied to the dissimilar metal welded body. The dissimilar metal welded body includes a first member made of a metal containing aluminum as a main component, a second member made of a metal containing copper as a main component, a welded portion formed by pressure-welding an end face of the first member and an end face of the second member to each other, and a metal film that continuously covers a substantially entire part of the first member and at least a part of the second member. The metal film is a film made of a metal containing copper as a main component.
