Abstract:
Provided is a configuration that makes up for a lack of tensile rigidity and a lack of collision properties at the same time. [Solution] An automotive exterior panel according to the present invention: an exterior material 110; and a reinforcing member 120 that is in contact along an automobile inside surface of the exterior material 110 and of which a second moment of area in a direction orthogonal to the exterior material is less than or equal to 15,000 mm4 in a cross section orthogonal to a longitudinal direction of the 10 reinforcing member. By this configuration, the second moment of area in a direction orthogonal to the longitudinal direction of the reinforcing member 120 is made less than or equal to 15,000 mm4, and hence a lack of tensile rigidity can be made up for at the same time.
