PROBLEM TO BE SOLVED: To provide a heat accumulating building material having strength and workability similar to an ordinary building material, and extremely easily maintaining comfortable room temperature over a long time by using an existing hollow building material as it is, in the heat accumulating building material fixed with a microcapsule containing a heat accumulating material. SOLUTION: A microcapsule solid material containing the heat accumulating material is filled in an inside space of the building material having a hollow structure. The average particle size of the microcapsule solid material is desirably in a range of 20μm to 30 mm. Desirably, this method uses the heat accumulating building material as an architectural interior material by using the microcapsule containing the heat accumulating material having a melting point in a range of 5 to 40°C, and uses the building material as a floor heating floor material by using the microcapsule containing the heat accumulating material having a melting point in a range of 30 to 80°C.
