Abstract
A vehicle body panel structure comprises an outer panel, an inner panel facing the outer panel, and a trim of a cabin interior. In the vehicle body panel structure, at least one surface of a back surface of the outer panel, both surfaces of the inner panel, and a surface of the trim facing the outer panel has both functions of heat insulation and heat dissipation by partially providing a heat insulation section to insulate heat for the at least one surface.
