Abstract: Provided is a method for forming a multilayer coating film that is capable of forming a multilayer coating film that has pearly luster with excellent blackness and high reflectance of an infrared laser. The method for forming a multilayer coating film includes applying a carbon black pigment-containing first colored paint (X) to form a first colored coating film; applying a second colored paint (Y) containing a pigment (A) that is a transparent or translucent base material coated with a metal oxide to form a second colored coating film; applying a clear paint (Z) to form a clear coating film; and heating the first colored coating film, the second colored coating film, and the clear coating film separately or simultaneously to cure these films, wherein the first colored coating film has a lightness L*(45°) of less than 20, the multilayer coating film has a lightness L*(45°) of less than 20, and the multilayer coating film has a diffuse reflectance of 10% or more at a wavelength of 905 nm.
