Abstract: A carbon fiber-reinforced resin molded body of the present invention derives from kneaded materials of a thermoplastic resin and a carbon fiber and includes at least a three-dimensional complex shaped region and a substantially flat plate-shaped region arranged in a profile direction. Fluidity of the kneaded materials at predetermined temperature is such that fluidity of the kneaded material forming the substantially flat plate-shaped region is lower than fluidity of the kneaded material forming the three-dimensional complex shaped region, which makes it unlikely to cause defects in ribs, posses, and other portions. Thus, a carbon fiber-reinforced resin molded body with low cost and high strength can be provided.
