In the 2nd. report the rerearch on the character of infra-red drying was discussed. In this paper, the mechanism of infra-red drying of "clay" is reported, being compared with convectiondrying. The critical moisture-content is lower in the former than in the latter drying. The drying process resembles to convection drying against high frequecy wave drying, the gradient of moisture-content towads the outer surface being very gentle. Consequenty, in drying of clay, the skin effect (that only very thin outer layer is dried) can be avoided. In drying of clay from 65% to 14% (in dry basis percentage), 1/2 in electric power and 2/5 in necessary time are seconsumedved comparing with convection-drying.
