PROBLEM TO BE SOLVED: To provide a microwave supplying apparatus which effectively enlarges the coagulation range of a tissue to be treated by setting the conditions for intermittently providing microwaves, and also to provide a microwave surgical apparatus provided with the microwave supplying apparatus.SOLUTION: On the basis of a first efficiency L2 of conduction heating by microwaves with respect to the cumulative emission time of microwaves emitted intermittently to a tissue to be treated and a second efficiency L1 of conduction heating by microwaves with respect to the cumulative emission time of microwaves emitted continuously to the tissue to be treated, and using as a reference a reference cumulative emission time Ti1 which is set in advance and serves as a cumulative emission time in which the first efficiency becomes larger than the second efficiency (L2 becomes smaller than L1), an output control section 6 of a microwave supplying apparatus controls a microwave emission section 5 so as to carry out microwave emission intermittently at least after the reference cumulative emission time Ti1.COPYRIGHT: (C)2015,JPO&INPIT【課題】マイクロ波を間欠的に供給する条件を設定することにより、被処置組織の凝固範囲を有効に広げたマイクロ波供給装置及びこの装置を備えたマイクロ波手術装置を提供する。【解決手段】マイクロ波供給装置の出力制御部6は、被処置組織に間欠的に照射されたマイクロ波の累積照射時間に対するマイクロ波による誘電加熱の第1効率L2と被処置組織に連続的に照射されたマイクロ波の累積照射時間に対するマイクロ波による誘電加熱の第2効率L1とに基づいて第1効率が第2効率よりも大きくなる(L2がL1よりも小さくなる)累積照射時間として予め設定された基準累積照射時間Ti1を基準として、少なくとも前記基準累積照射時間Ti1の後のマイクロ波の照射を間欠的に行うように前記マイクロ波発生部5を制御する。【選択図】図1
