PROBLEM TO BE SOLVED: To uniformly heat and dry an object to be dried by increasing the entering area of microwave electric power to the object and to suppress the degradation of heating efficiency by minimizing reflected microwave electric power in a microwave dryer. SOLUTION: A container 13 formed of a microwave transmitting material is provided in a metallic drying vessel 1, and the object 14 to be dried is put in the container 13. A resonance adjusting plate 11 is provided in the drying vessel 1, and its position is feedback-adjusted to reduce the reflected electric power of microwave reflected from the drying vessel 1. Further, a wave guide body 15 formed of a microwave transmitting material is inserted in the container 13 from the surface of the object 14 to be dried. The entering area of microwave electric power to the object 14 to be dried can thereby be increased. COPYRIGHT: (C)2007,JPO&INPIT
