PROBLEM TO BE SOLVED: To provide a resin molded article capable of suppressing generation of burrs and the like when executing welding joint by irradiation of laser light.SOLUTION: A resin molded article is formed by joining, with laser irradiation, an output-side housing part 3 exhibiting a laser transmitting property for transmitting laser light and an input-side housing part 2 exhibiting a laser absorbing property for absorbing laser light. The input-side housing part 2 includes a protruded part 21 which is fused by receiving laser irradiation while being abutted against the output-side housing part 3 and bonded to the output-side housing part 3. Further, the input-side housing part 2 includes recessed parts 22 and 23 which are provided to locate on both sides of the protruded part 21 and house at least a part of the protruded part 21 that is fused by the laser irradiation.SELECTED DRAWING: Figure 4
【課題】レーザ光の照射によって溶着接合した場合にバリ等が生じることを抑制できる樹脂成形品を提供する。【解決手段】樹脂成形品は、レーザ光を透過するレーザ透過性を有する出力側ハウジング部3とレーザ光を吸収するレーザ吸収性を有する入力側ハウジング部2とがレーザ照射によって接合されて構成される。入力側ハウジング部2は、出力側ハウジング部3に突き合わされた状態でレーザ照射によって溶融して出力側ハウジング部3に接着する凸部21を有する。さらに入力側ハウジング部2は、凸部21に対して両側に位置するように設けられ、レーザ照射によって溶融した凸部21の少なくとも一部を収容する凹部22及び凹部23を有する。【選択図】図4
