[PROBLEMS] To provide novel means for introducing a microwave having an extremely wide frequency band and an extremely high output level efficiently with respect to the resonance load. [MEANS FOR SOLVING PROBLEMS] A microwave device comprises a voltage-controlled solid-state oscillator (1) for generating a microwave, a microwave amplifier (3) for amplifying the output of the oscillator (1), a TM010-mode cylindrical cavity resonator (2) which the output of the amplifier (3) is made to enter, a sensing element (7) coupled to the cavity resonator (2) and adapted for sensing the electromagnetic field inside the cavity resonator (2), a feedback control means (8) for controlling the oscillator (1) according to the output signal from the sensing element (7) so that the oscillation frequency of the oscillator (1) may match the present resonance frequency of the cavity resonator (2), and a subject-holding tubular member which is permeable to a microwave, is disposed inside the cavity resonator (2) generally coaxially with the central axis of the cavity resonator (2), and holds therein a subject (S) to be irradiated with a microwave. |
