PROBLEM TO BE SOLVED: To provide a trim material having an undulated surface constituted by molding an arbitrary undulated shape to the surface of a skin material at the same time during a process for integrally molding the skin material and a thermoplastic resin, and its molding method. SOLUTION: After the skin material 1, which is produced by laminating a fabric 1a, a cushion layer 1b and a back base fabric 1c from a surface side, is set to the inside of a mold, a molten thermoplastic resin 3 is injected to mold the trim material wherein the skin material 1 and the thermoplastic resin 3 are integrated, a fabric, which has a difference in its heat shrinkage factor in its longitudinal and lateral directions and is prepared by welding the fabric 1a and the back base fabric 1c through the cushion layer 1b in a dot form at least at two points in the direction large in the heat shrinkage factor, is used as the fabric 1a. By this constitution, the fabric 1a is shrunk between the dot like welded parts 2 and 2 by the heat received from the molten resin at the time of injection of the molten thermoplastic resin in the mold so as to be biased in the direction large in the shrinkage factor to form recessed stripe patterns 4 to the surface of the skin material 1.
