The present invention addresses the problem of providing a resin molded article capable of improving the bonding strength between a first member and a second member. The present invention is a resin molded article (1) in which a first member (5) and a resin second member (6) are integrally molded. The resin molded article (1) is provided with an extending protrusion (9) which is formed by the second member (6) and which is located on the outside of at least a part of the outer edge (8) of the first member (5). The resin molded article (1) is provided with a gate section (11) which is disposed on the extending and protruding section (9) and into which the molten resin raw material flows during molding. The first member (5) has an area-enlarged portion (13) at an outer edge portion (8) that is in contact with the extension protrusion (9) and that extends in the flow direction of the molten resin raw material from the gate portion (11).
本发明的课题在于提供一种能够提高第一部件与第二部件的接合强度的树脂成型品。本发明为第一部件(5)和树脂制的第二部件(6)成型为一体的树脂成型品(1)。树脂成型品(1)具有延伸突出部(9),所述延伸突出部(9)由第二部件(6)形成,且相对于第一部件(5)的外缘部(8)的至少一部分位于外侧。树脂成型品(1)具有浇口部(11),所述浇口部(11)配置于延伸突出部(9),且为在成型时熔融树脂原料流入的部分。第一部件(5)在与延伸突出部(9)接触且沿着来自浇口部(11)的熔融树脂原料的流动方向的外缘部(8)具有面积扩大部(13)。
