PROBLEM TO BE SOLVED: To provide an interior material for a vehicle which can increase acoustic absorption performance without an increase in a thickness of an acoustic absorbing material or the like.SOLUTION: A plurality of slits 12 that section cut and raised regions at required intervals in an acoustic absorbing material 11 are provided to form cut and raised pieces 13 from the respective slits, and a surface of the acoustic absorbing material 11 is formed into an uneven shape by a plurality of the cut and raised pieces 13. Consequently, a surface area for absorbing sounds of the acoustic absorbing material 11 is increased, and a rear air space S is formed between a trim material 10 and the acoustic absorbing material 11. As a result, acoustic absorption performance of the acoustic absorbing material 11 is increased, and an acoustic absorption effect by the rear air space S is obtained. |
