PROBLEM TO BE SOLVED: To provide a method for integrally molding a skin using injection molding or injection and compression molding capable of preventing the nap falling and warpage of a raised skin material. SOLUTION: In the method for integrally molding the skin, the temperature of a mold on a skin material side is held to a temperature lower than the thermal deformation temperature of a filling resin in the whole process while the temperature of a mold on the side opposite to the skin material is held so as to become a temperature range from the thermal deformation temperature of the filling resin to the melting temperature thereof from the filling with a resin to the completion of a slight opening/raising process. After the completion of the slight opening/raising process, the temperature of the mold on the side opposite to the skin material is lowered to a temperature lower than the thermal deformation temperature of the filling resin and, at the point of time when the temperature of the skin material falls sufficiently, mold clamping pressure is made zero or the mold is stopped at an experimentally calculated position supporting a molded product without collapsing raising to be held for a set time.
