To provide a resin structure having a high bonding strength between a substrate and a resin member, and being less prone to bumps and dips due to a protruding part on a surface opposite to a surface to which the resin member is bonded, in the substrate, and a method for manufacturing the resin structure.SOLUTION: A resin structure 10 comprises: a tabular substrate 12 containing a thermoplastic resin; and a resin member 20 bonded to one surface 12B of the substrate 12. In the resin member 20, on a bonding surface 21 being a bonding portion to the substrate 12, a protruding part 22 is provided which protrudes inside the substrate 12 from the bonding surface 21. The protruding part 22 comprises: a base part 23 that extends from the bonding surface 21 toward the substrate 12 inside the substrate 12; and a crossing part 24 that continues to the tip side of the base part 23 and extends in a direction that intersects the protruding direction of the base part 23 from the bonding surface 21.SELECTED DRAWING: Figure 7
【課題】基材と樹脂部材との接合強度が高く、なおかつ、基材において樹脂部材が接合された面の反対面に突出部に起因する凹凸が生じ難い樹脂構造体および樹脂構造体の製造方法を提供する。【解決手段】熱可塑性樹脂を含む板状の基材12と、基材12の一方の面12Bに接合された樹脂部材20と、を備え、樹脂部材20のうち基材12との接合部分である接合面21に、当該接合面21から基材12の内部に突出する突出部22が設けられており、突出部22は、基材12の内部において、接合面21から基材12に向けて延びる基部23と、基部23の先端側に連なり、基部23の接合面21からの突出方向と交差する方向に延びる交差部24と、を備える、樹脂構造体10。【選択図】図7
