PROBLEM TO BE SOLVED: To house a resin molded product part A by accurately positioning the resin molded product part A molded on a resin sheet S irrespective of change of shrinkage percentage of the resin sheet S in a recessed part of a trimming die. SOLUTION: A female mold 1 in which a plurality of cavities 3 are formed, a male mold 2 made freely separable from and contactual to relatively to the female mold 1 opposed to those cavities 3, and a pressure generation means wherein a pressure difference is generated between the female mold 1 side and the male mold 2 side of the cavity by putting a resin sheet S between are provided. On at least one end surface of the mutually opposed end surfaces 1A and 2A of the female mold 1 and the male mold 2, a cutting edge 13 protruding to the other end surface side is intermittently provided in each space between the cavities in a part between the mutually neighbouring cavities 3. Thereby, between resin molded product parts A molded mutually adjacent to each other on the resin sheet S, a cut notch M passing through the resin sheet S is formed without being continued to the cut notch M between that and another resin molded product part A.
