A multilayer coating film includes a lustrous layer directly or indirectly formed on a surface of a coating target and 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.
