A decorative film structure includes: a surface layer constituted by a transparent or translucent resin layer; an achromatic layer constituted by dots provided on a back surface of the surface layer; and a metal luster 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 μm or less and either an Rmax is 4 μm or less or a Sm is 50 μm or more. A lightness L* of the achromatic layer is 0-80. An area of each dot when viewed from a front side of the surface layer is 10−3-105 μm2. A dot area percentage per a unit area when viewed from the front side of the surface layer is 1-80%. A stimulus value Y45° of the metal luster layer is 10000 or more.
