An object of the present invention is to provide a heat insulating material that can be easily stored with microwaves, for example, can be stored in a microwave oven in a general household, and can be reused. Furthermore, the heat insulating material of the present invention can ensure heat retention for a long time by microwave irradiation, and can further suppress cracking and deterioration due to volume expansion accompanying microwave irradiation. The heat insulating material of the present invention is characterized in that the organic latent heat storage material (a) is fixed by a binder (b) containing a segment that vibrates and generates heat by microwaves.
