The present invention relates to a sound absorbing/insulating material for vehicle. The sound absorbing/insulating material for vehicle according to the present invention is made of a polyester foam sheet having a high closed cell ratio, and thus has excellent lightweight and external sound insulating properties. The polyester foam sheet simultaneously satisfies excellent blocking performance and sound-absorbing performance by including non-penetrating holes of specific depth and diameter.
