PROBLEM TO BE SOLVED: To provide a vehicular undercover capable of attaining high stiffness, chipping resistance and thermal moldability. SOLUTION: This vehicular undercover is composed of a resin composition including the following propylene-ethylene block copolymer (A). The propylene-ethylene block copolymer (A) is composed of 95 to 60 wt% single propylene polymer portion (A1), and 5 to 40 wt% propylene-ethylene copolymer portion (A2). An intrinsic viscosity [η]ep of the single polymer portion (A1) is 2 to 5 dl/g. An ethylene content contained in the copolymer portion (A2) is 20 to 50 wt%. An intrinsic viscosity [η]ep of the copolymer portion (A2) is 2 to 8 dl/g. COPYRIGHT: (C)2006,JPO&NCIPI
