• The development of the method of quick determination of water content by microwaves has being watched with keenest interest by soil mechanics and foundation engineers. A certain number of experimental works have made it clear that the microwave oven functions well for the present compared to JIS method. In detailed observation, usually it was observed in a conventional oven that soil sample with low wet density required shorter than the time for drying of the one with high wet density. But, due to the nature of the action of the microwave, the trend contrary to this was observed in a microwave oven. Therefore, in order to explain this phenomenon, internal temperature of soil specimen was measured by a digital thermometer. As a result, it was obtained that the typical two internal temperature- drying time curves corresponded to the typical two degree of drying-drying time curves in a microwave oven; a series of curves were observed for compacted soil sample, in which a digital thermometer registered 120℃ at maximum temperature, and the other series of curves were observed for disturbed soil sample, in which the thermometer registered less than 110℃ at maximum temperature.
