Summary:To provide a resin-containing material structure that makes possible to suppress a development of damage due to peeling between resin-containing materials in a resin-containing material structure obtained by adhering the resin-containing materials with an adhesive and a production method of the resin-containing material structure.SOLUTION: A resin-containing material structure includes a first resin-containing material, a second resin-containing material, and an adhesive. The adhesive layer has a structural adhesive region formed by providing a structural adhesive having high rigidity after adhesion of the first resin-containing material and the second resin-containing material, and a high loss tangent adhesive-containing region formed by containing a high loss tangent adhesive having a higher loss tangent than the structural adhesive after adhesion of the first resin-containing material and the second resin-containing material. The structural adhesive region is provided at a center region of an adhesive surface between the first resin-containing material and the second resin-containing material, and the high loss tangent adhesive-containing region is provided on at least a part of an outer periphery of the structural adhesive region.SELECTED DRAWING: Figure 3 【課題】樹脂含有材料を接着剤等で接着することで得られる樹脂含有材料構造体において、樹脂含有材料間の剥離による損傷の進展を抑制することを可能にした樹脂含有材料構造体及び樹脂含有材料構造体の製造方法を提供すること。【解決手段】樹脂含有材料構造体は、第１樹脂含有材料と、第２樹脂含有材料と、接着剤層と、を含む。接着剤層は、第１樹脂含有材料と第２樹脂含有材料とを接着後に高剛性を有する構造用接着剤が設けられて形成された構造用接着剤領域と、第１樹脂含有材料と第２樹脂含有材料とを接着後に構造用接着剤よりも高い損失正接を有する高損失正接接着剤を含んで形成された高損失正接接着剤含有領域と、を有する。構造用接着剤領域は、第１樹脂含有材料と第２樹脂含有材料との接着面の中央領域に設けられ、高損失正接接着剤含有領域は構造用接着剤領域の外周の少なくとも一部に設けられている。【選択図】図３
