A vehicular resin panel structure including: an outer panel that includes an outer panel main body and an outer edge portion formed by bending an edge portion of the outer panel main body toward one side in a plate thickness direction of the outer panel main body; and a resin inner panel that includes an inner panel main body that is joined to the outer panel main body by an adhesive, and an inner edge portion that is formed by bending an edge portion of the inner panel main body toward another side in the plate thickness direction. A leading end portion of the inner edge portion abuts the outer panel main body, and a parting line during molding is formed at a location separated from the leading end portion.
