PROBLEM TO BE SOLVED: To provide a synthetic resin product not bringing about the deterioration of a hue and a pattern with the elapse of time and having a high grade feeling, especially a temple for glasses, a front member for the glasses, the glasses and a manufacturing method of the synthetic resin product. SOLUTION: The synthetic resin product is constituted of a synthetic resin body and a metal core and the synthetic resin body is made transparent at least on the side opposed to the printing surface applied to the metal core thereof while the hue and the pattern are printed on the surface of the metal core inserted in the synthetic resin product by printing ink. Further, the printed surface is coated with a coating resin having a heat-resistant temperature not lower than that of the printing ink and, after this coated printed surface is dried and fixed, the metal core is heated to 250-350°C to immediately partially melt the metal core heated from the end part thereof to press the partially melted metal core into the synthetic resin body before cooling and fixing the same.
