Abstract
A polyurethane foam of the present disclosure is obtained from a polyurethane raw material containing a polyol component and a polyisocyanate component, and a gas for foaming. The polyurethane raw material contains a hydrophobic silica as a foam retention agent for retaining a foam and a light calcium carbonate, and the light calcium carbonate is 10 parts by weight or more based on 100 parts by weight of the polyol component.
