摘要：A method for manufacturing a resin molding can be provided that uses a laser

beam. The method can include providing the resin molding including welded portionsthat can impart high level of adhesion, have excellent appearance and provide verystrong bonding strength. The method can also include arranging and pressing a weldregion of a light-absorbing resin member and corresponding weld region of a light-transmitting resin member that are opposed to each other, and setting a plurality ofirradiation areas in the extending direction of the welded regions. The method can alsoinclude arranging a plurality of laser irradiation scanning heads corresponding to theirradiation areas. Here, the irradiation areas can include a single irradiation area which thecorresponding scanning head can irradiate with the laser beam and a compositeirradiation area which the adjacent scanning heads can irradiate with respective laserbeams. The method can further include causing the plurality of laser beams emitted fromthe scanning heads to repeatedly scan the single irradiation area along a first trajectoryin the extending direction of the single irradiation area and part of both the singleirradiation area and the composite irradiation area along a second trajectory in theextending direction, so that the entire welded regions are heated and fused to weld thelight-transmitting resin member and the light-absorbing resin member.
