Estimating the term…
In the present invention, it is possible to reduce the occurrence of a local deformation in a plate material during solidification and shrinkage of an injection molding material. The composite material injection molding method includes an injection step of injecting an injection molding material containing reinforcing fibers onto one surface of a plate material; and a molding step of solidifying the injection molding material to mold a frame part so as to surround the outer periphery of the plate material and to mold a rib so as to define an inner peripheral-side space on the inner peripheral side of the frame part. In the injection step, the injection molding material is injected so that a weld part at which the injection molding material converges is formed in a region not overlapping the plate material of the frame part.
