PROBLEM TO BE SOLVED: To provide a sheet material which brings about an effectual far infrared radiation effect by selecting a far infrared radioactive material capable of radiating good quality far infrared rays to human bodies, and handling it under an optimum condition, and an architectural heating material arranged by using the sheet material, and a method for manufacturing the sheet material.SOLUTION: The sheet material S generates heat when put in electrical conduction. The sheet material S comprises, at least, a base fabric 11 prepared by weaving fiber threads, and Bakuhan-seki powder 22 prepared by pulverizing a bulk of Bakuhan-seki, which is a far infrared radioactive material. The Bakuhan-seki powder 22 has a particle diameter of 0.9-50 μm. |
