Abstract
A multilayer coating film includes a lustrous layer containing a luster material, and a colored layer stacked on the lustrous layer, containing a reddish coloring agent, and having translucency. For the lustrous layer, when a light incident angle (an angle with respect to a line perpendicular to the surface of the lustrous layer) is 45° and L*(θ) represents the L* value of the lightness index of reflected light measured at a light receiving angle (the angle of inclination toward a light source side from a specular reflection direction) θ, L*(θ) at 45°≤θ≤80° and 100°≤θ≤110° is 10 or less, and when the luster material is projected onto the bottom surface of the lustrous layer, the percentage of the projected area of the luster material on the bottom surface is 3% or more to 70% or less per unit area.
