The present invention provides a foam sheet for a car interior member which is capable of being molded into a desired shape while keeping an excellent sound absorbency. The foam sheet for a car interior member according to the invention comprises a modified polyphenylene ether-based resin foam sheet having an open cell ratio of 50% or more, and the modified polyphenylene ether-based resin foam sheet has pore portions formed in a single face thereof so as to be open to the face thereof. Accordingly, vibration energy of sounds is smoothly induced through the pore portions to the open cells of the foam sheetto vibrate cell walls of the open cells, thereby converting the vibration energy to thermal energy. Thus, an excellent sound absorbency is exhibited.
