<p>It is intended to provide a building material which has an effect of promoting human health. A far infrared radiation material containing animal and plant plankton fossils collected from a place, which was once the sea bottom such as a continental shelf but is now a land area, is ground into a nanopowder, evaporated by the heat deposition method and thus fixed to a building material. By fixing the far-infrared radiation material at the nano level to the surface and inner face of the building material, far-infrared ray, which is efficacious in promoting human health, can be radiated at ordinary temperatures without resorting to any external factors (for example, rubbing, heating, pressurizing, etc.) so that the health of inhabitants can be promoted.</p> |
