Claim 0:
1. A foam comprising:
a modified cellulose fiber (A) in which a cellulose fiber is covalently bonded with a diene-based polymer (a);
a thermoplastic resin (B); and
an unreacted diene-based polymer (C) having a functional group capable of covalently bonding with the cellulose fiber, wherein
the modified cellulose fiber (A) is micronized,
a content amount of the modified cellulose fiber (A) is 0.05 to 20% by mass with respect to the foam,
the thermoplastic resin (B) has a glass transition point of −130° C. to 120° C., and
a mass ratio is (A)/(B)/(C)=1/1.5 to 2000/0.001 to 0.5.
