摘要： An injection molded body includes a fiber reinforced thermoplastic resin composition formed by combining fibrous filler with thermoplastic resin so that the weight average fiber length in the injection molded body is 300 μm or more, and the injection molded body has a skin layer, a core layer and a skin layer in this order in the thickness direction. The thickness of the core layer, in which the primary orientation direction of the fibrous filler is 40° or less when the direction perpendicular to the flow direction of the resin composition at the time of injection molding is set at 0°, is 20% or less relatively to the thickness of the injection molded body.
