In a vehicle back door main body, an outer upper panel made of CFRP is joined to an upper portion of an inner panel made of CFRP, and an outer lower panel made of a resin weaker than CFRP is joined to a lower portion of the inner panel. Of an outer edge portion of this back door main body, an upper portion side is a first outer edge portion that is reinforced by the outer upper panel, and a lower portion side is a second outer edge portion having a lower strength than the first outer edge portion. Also, a boundary portion between the first outer edge portion and the second outer edge portion where there is a strength difference is set at a portion weakened by being adjacent to a small window opening.
