A cross section of a composite material molded product includes a hollow portion, a bent portion or a curved portion. If, for example, the composite material molded product has a bent portion, a surface forming the inside of the bent portion is set as a pressed surface. A molding die (10A) is provided with: a thermally expanding pressing body (13A) having an outer surface shape that corresponds to the shape of the pressed surface; and a molding die main body (a female mold portion (11), a side surface lid mold portion (12) and the like) which is provided with a cavity internally accommodating a stacked body (40) and the pressing body (13A), and in which the cavity (11b) includes an inner surface shape corresponding to the shape other than the pressed surface. The molding die main body is configured in such a way that the cavity is sealed in a state in which the pressing body (13A) is disposed in the cavity, and the stacked body (40) is accommodated in a molding space (15) formed between the inner surface of the cavity and the outer surface of the pressing body (13A). It is to be noted that in the composite material molded product, the surface which will form the outside of the bent portion or the curved portion may be a pressed surface.
