PROBLEM TO BE SOLVED: To provide a fluororesin molded product which exhibits excellent adhesion to a colored coating film, in place of a conventional colored fluororesin molded product using a colored batch. SOLUTION: The colored fluororesin molded product is obtained by the followings. The surface of a fluororesin containing (a) at least one functional group selected from the group consisting of an acid anhydride residue, a carboxy group, a hydroxy group, an epoxy group, a hydrolytic silyl group, an alkoxycarbonyl group and an acid halide group, is coated with a colored coating agent having (b) a functional group reactive to the above-described functional group, followed by a thermal treating at a temperature substantially progressing the reaction of the functional group. The thermal treatment of the colored fluororesin molded product by the coating is preferably carried out at a temperature which is lower than the melting point of the fluororesin and is the same as or higher than the temperature 100°C below the melting point.
