Abstract: A method for manufacturing a shaped product includes 1) heating at least three prepregs having a thickness of 0.3 mm to 5.0 mm each including reinforcing fibers having an average fiber length of 3 to 100 mm and a thermoplastic resin, 2) arranging those prepregs so as to constitute at least two layers including P layer and Q layer which are in contact with each other, and 3) then pressing those layers to manufacture one shaped product. A prepreg (p1) in the P layer and a prepreg (q1) in the Q layer are arranged such that at least a part thereof overlaps with each other, and two or more prepregs in the same layer are arranged so as not to be in contact with each other.
