Abstract
A layered coating film according to the present invention includes a lower coat 30 including a first coloring material and a bright material, and an upper coat 20 superposed on the lower coat and including a second coloring material. The upper coat and the lower coat have similar colors. The refractive index of a film constituent of the lower coat other than the first coloring material is higher than the refractive index of a film constituent of the upper coat other than the second coloring material.
