PROBLEM TO BE SOLVED: To economically provide a fiber-reinforced thermoplastic resin molded product capable of sufficiently exhibiting characteristics possessed by reinforcing fibers and having shaping properties together with strength. SOLUTION: This fiber-reinforced thermoplastic resin molded product comprises 40-95 mass% of a thermoplastic resin and 5-60 mass% of the reinforcing fibers having 0.3-25 mm average fiber length and has >=30 and <95% degree of fiber orientation of the reinforcing fibers. The fiber-reinforced thermoplastic resin molded product can be produced by laminating a flat plate made of the thermoplastic resin onto a reinforcing fiber fabric and carrying out thermocompression forming of the resultant laminate.
