<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive far-infrared radiation plate which has sufficient strength, and can efficiently generate far-infrared rays from a wide area. <P>SOLUTION: Disclosed is a far-infrared radiation plate 10 radiating far-infrared rays, obtained by adding a binder to a far-infrared radiation material composed of aggregate with a particle size of 2 to 8 mm and fine aggregate with a particle size of 0.1 to <2 mm and hardening the same. The inside thereof is provided with a facial reinforcing member 11, the aggregate is composed of natural ore-pulverized matter and slag-pulverized matter, the fine aggregate is composed of natural ore-pulverized matter and waste glass-pulverized matter, and the ratio of the fine aggregate to the aggregate is 0.8 to 2.5. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
