To provide a roof tile and a snow-melting roof using the same, which are epoch-making in terms of lightness in weight, weatherability, corrosion resistance, unsusceptibleness to a change in humidity and ease of manufacture.

This roof tile is composed of fire-resistant CRB ceramics which are ceramic materials manufactured as follows: defatted rice bran, which is obtained from rice bran, and a thermosetting resin are taken as carbonized powder by pulverization after being mixed for kneading so as to undergo primary burning at 700-1,000°C in an inert gas; a ceramic powder, a solvent and a binder, which is added according to need, are mixed for kneading into the carbonized powder in order to be taken as plastics (paste), and pressurized for molding with a pressure of 10-100 MPa; and after that, a molding is re- treated with heat at 500-1,400°C in an atmosphere of an inert gas.
