<p><P>PROBLEM TO BE SOLVED: To provide a snow melting floor material for stairs, which is excellent in cost efficiency, snow melting performance, and anti-skid properties, and is free from limitation of installation district or installation location. <P>SOLUTION: According to the structure of the snow melting floor material, front and rear surfaces of an energizing/heating body 2 having a pair of watertight terminals 20, are hermetically sealed with a front sheet 3 formed of a synthetic resin and/or rubber as a main component and uniformly containing therein far-infrared emitted powder 5, and a rear sheet 4 formed of a synthetic resin and/or rubber as a main component and excellent in heat insulation properties. Then the energizing/heating body is bent at about 90 degrees toward the rear surface in order to follow the shape of a staircase substrate, and a tread 10, a nosing 11, and a riser 12 are sequentially formed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
