PROBLEM TO BE SOLVED: To provide a multi-color molding resin window member which is a multi-color molding resin window member including a transparency window layer and a window frame layer laminated around the transparency window layer, is hard to start brittle fracture to shock, and is excellent in safety. SOLUTION: The multi-color molding resin window member includes: a transparency window layer which composes a transparency window part; and a window frame layer prepared by being laminated in at least a part of the transparency window layer around the transparency window part, wherein the adhesion force of the transparency window layer and the window frame layer is 35-90 MPa, and the transparency window layer does not carry brittle fracture in a falling weight impact test in a boundary section of the window frame layer laminate section and a non-laminate section of the transparency window layer.
