RESIN STRUCTURE AND METHOD OF MANUFACTURING RESIN STRUCTURE

To provide a resin structure and a method for manufacturing the resin structure that can improve welding strength while suppressing reduction in overall rigidity.SOLUTION: A resin structure 2 includes a first resin member 21 and a second resin member 22 welded to each other. The first resin member 21 and the second resin member 22 respectively include: main body portions 213 and 222; and low crystalline layers 214 and 223 formed on a surface portion and having lower crystallinity than the main body portions 213 and 222. The first resin member 21 and the second resin member 22 are welded to each other in the low crystallinity layers 214 and 223 of the first resin member 21 and the second resin member 22.SELECTED DRAWING: Figure 1 【課題】全体の剛性の低下を抑制しつつ溶着強度を向上させることができる樹脂構造体及び樹脂構造体の製造方法を提供する。【解決手段】樹脂構造体２は、互いに溶着された第１樹脂部材２１及び第２樹脂部材２２を備える。第１樹脂部材２１及び第２樹脂部材２２のそれぞれは、本体部２１３，２２２と、表面部に形成され、本体部２１３，２２２よりも結晶性の低い低結晶性層２１４，２２３とを有する。第１樹脂部材２１と第２樹脂部材２２とは、第１樹脂部材２１及び第２樹脂部材２２の低結晶性層２１４，２２３において、溶着されている。【選択図】図１
