| abstract | An object of the present invention is to provide a building material excellent in foamability, heat-fusibility and heat resistance. A building material as a heat insulating material includes a resin containing a component derived from an ester of a polycyclic terpenol having 10 to 20 carbon atoms and methacrylic acid and a component derived from a styrene monomer, and a volatile foaming agent (1) The resin is more than 1 part by weight of the component derived from the ester with respect to a total of 100 parts by weight of the component derived from the ester and the component derived from the styrene monomer. (2) It has a surface layer with an absorbance ratio X (D1730 / D1600) in the range of 0.35 to 6.00 (D1730 and D1600 are 1730 cm in the infrared absorption spectrum by infrared spectroscopy). It means the absorbance at the absorbance and 1600 cm -1 in -1), expandable polystyrene having a central portion (3) the absorbance ratio X is less than the absorbance ratio Y (D1730 / D1600) The building material characterized by comprising a foamed molded article of the system resin particles to solve the above problems.
