A coating of an outer plate contains a perylene-based pigment, and satisfies (R/R)&#x2265;74, where Ris the highlight reflectance of the coating of the outer plate at a peak wavelength at which reflectance reaches the maximum value in a spectral reflectance curve, and Ris the average highlight reflectance of the coating of the outer plate in a complementary wavelength range. A coating of an inner plate part contains a perylene-based pigment and an iron oxide-based pigment, the content of the perylene-based pigment in the coating of the inner plate part is in units of PWC, and the mass ratio of the content of the iron oxide-based pigment to the content of the perylene-based pigment in the coating of the inner plate part is 3-20%.

Coating of inner plate part of vehicle

A decorative film structure includes: a surface layer constituted by a transparent or translucent resin layer; a metal luster layer constituted by dots provided on a back surface of the surface layer; and an achromatic layer provided on the back surface of the surface layer to fill a gap between the dots. As surface roughness of a front surface of the surface layer, an Ra is 2 &#x3bc;m or less and either an Rmax is 4 &#x3bc;m or less or a Sm is 50 &#x3bc;m or more. A stimulus value Y45&#xb0; of the metal luster layer is 10000 or more. An area of each dot when viewed from a front side of the surface layer is 10-10&#x3bc;m. A dot area percentage per a unit area when viewed from the front side of the surface layer is 20-99%. A lightness L* of the achromatic layer is 0-80.
