(57) [Summary] [Problem] To reduce the weight of the entire vehicle by sufficiently reducing the weight of the vehicle, and to eliminate the discomfort when touching the skin material mounting portion and improve the feeling of touch. And a method for molding the same. SOLUTION: An automobile door panel 10 has a skin material 12 attached to a part of a base material 2 made of a glass fiber-containing polypropylene resin, and a specific gravity of a non-skin material portion where the skin material 12 is not attached is zero. 0.4 to 0.6, the specific gravity of the skin material mounting portion to which the skin material 12 is mounted is 0.5 to 0.9, The base material 2 comprises 100 parts by weight of a polypropylene resin composition satisfying predetermined conditions and 15 to 25 parts by weight of an ethylene-butene copolymer elastomer. Therefore, satisfactory impact resistance and strength are satisfied, and a springback phenomenon can be obtained, which contributes to weight reduction. |
