PROBLEM TO BE SOLVED: To provide an inexpensive monolithic mold superior in an external appearance characteristic and a feel characteristic, and its molding method. SOLUTION: A sewing-up part 6 of skin materials 2A and 2B tucked inside a skin body 2 is covered/wrapped with a flexible water impermeable sheet material 5 from the inside of the skin body 2. Such constitution can prevent leakage of a foaming resin material by covering/wrapping an expansion part with the sheet material 5 even if a needle hole 8 expands when the sewing-up part 6 is drawn out by foaming pressure of the foaming resin material, and can surely prevent impregnation of the liquid foaming resin material into the sewing-up part 6 side by the sheet material 5, and can also dispense with postprocessing work caused by the leakage of the foaming resin material, so that the inexpensive skin integrated mold superior in both the external appearance characteristic and the feel characteristic and having a high commodity value can be provided as these synergistic effects.
