<p><P>PROBLEM TO BE SOLVED: To provide a resin molded object which uses a PAS resin (polyarylene sulfide resin) on the side to be irradiated with a laser light and has sufficient joining strength. <P>SOLUTION: This resin molded object is obtained by superposing two different kinds of resin materials over each other and weld-joining the resin materials by irradiation with a laser light as a heating source from one side. The resin material on the side to be irradiated with the laser light, is constituted of a resin material containing the PAS resin. In addition, the resin material to be superposed over the resin material on the side to be irradiated with the laser light is a resin material containing not less than one kind selected from the group consisting of a polyarylene sulfide resin, a polyamide resin, a polyolefin and a styrene-acrylonitrile copolymer. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
