Abstract
A multilayer coating film includes a lustrous layer containing a luster material and a colored layer containing a reddish coloring agent, and having translucency. Regarding a Y value of an XYZ colorimetric system calibrated with a standard white plate, when a light incident angle is 45°, Y(5°) represents a Y value of reflected light measured at a light receiving angle of 5°, and Y(15°) represents a Y value of reflected light measured at a light receiving angle of 15°, the lustrous layer satisfies the following: Y(5°) is 30 or more to 700 or less; Y(15°)=k×Y(5°) (where k is a coefficient); and k is 0.01 or more to 0.3 or less. The concentration of the reddish coloring agent in the colored layer is 1 mass % or more to 17 mass % or less.
