A plated polyester resin article composed of a polyester resin molded article and, formed on the surface thereof, a metal plating layer, characterized in that the polyester resin article has been crosslinked by the irradiation of an ionizing radiation, the plating layer has an arithmetic average roughness of 1 mum or less, and the adhesion strength between the polyester resin article and the metal plating layer is 2 MPa or higher; and a method for producing the plated polyester resin article, which comprises a step of subjecting a resin composition comprising a polyester resin capable of being crosslinked by the irradiation of an ionizing radiation and, dispersed therein in a proportion of 5 to 20 vol %, an inorganic filler having an average particle diameter of 1 to 10 mum to melt molding into a polyester resin molded article. L'invention concerne un article en résine polyester plaqué, composé d'un article moulé en résine polyester et d'une couche de placage métallique formée à la surface de cet article, caractérisé en ce que l'article en résine polyester est réticulé par irradiation au moyen d'un rayonnement ionisant, la couche de placage présente une rugosité moyenne arithmétique égale ou inférieure à 1 mu m, et la résistance à l'adhérence entre ledit article en résine polyester et la couche de placage métallique est égale ou supérieure à 2 Mpa. L'invention concerne également un procédé de production d'un article en résine polyester plaqué, procédé consistant à soumettre une composition de résine apte à être réticulée par irradiation au moyen d'un rayonnement ionisant, renfermant une charge inorganique d'un diamètre de particule moyen de 1 à 10 mu m dispersée dans cette composition, à un moulage par fusion dans un article moulé en résine polyester.
