Described herein is a topcoat paint composition having an acrylic resin (A) and a melamine resin (B). The acrylic resin (A), relative to 100 parts by mass thereof, contains 30-40 parts by mass of 2-hydroxyethyl methacrylate, 10-30 parts by mass of styrene and 25 parts by mass or more of 2-ethylhexyl acrylate, and does not contain, relative to 100 parts by mass of the acrylic resin (A), more than 5 parts by mass of caprolactone compound(s) and/or hydroxy group-containing (meth)acrylates constituted of 7 or more carbons. The content of acrylic resin (A), relative to 100 parts by mass of total resin solids of the topcoat paint composition, is 45 parts by mass or more. The content of melamine resin (B), which does not contain complete alkyl ether type melamine resin, relative to the acrylic resin (A), as resin solids ratio, is acrylic resin (A)/melamine resin (B)=50/50 to 80/20.
