MICROWAVE IRRADIATION DEVICE AND MICROWAVE IRRADIATION METHOD

To provide a microwave irradiation device capable of efficiently heating a predetermined portion of an object irradiated with a microwave.SOLUTION: A microwave irradiation device 1 comprises: a microwave generator 11 that generates a microwave; a wave guide pipe 12 for transmitting the microwave from the microwave generator 11, having a taper part 22 in which a cross section orthogonal to a longitudinal direction of the wave guide pipe 12 is gradually reduced as directing to an open of a tip end of the wave guide pipe 12; and a movement part 13 that makes an object 3 irradiated with the microwave move so as to pass the tip of the taper part 22.SELECTED DRAWING: Figure 1 【課題】マイクロ波の照射対象物の所定の箇所を効率よく加熱することができるマイクロ波照射装置を提供する。【解決手段】マイクロ波照射装置１は、マイクロ波を発生させるマイクロ波発生器１１と、マイクロ波発生器１１からのマイクロ波を伝送するための導波管１２であって、導波管１２の長手方向に直交する断面が導波管１２の先端の開口に向かって徐々に小さくなるテーパ部２２を有する導波管１２と、テーパ部２２の先端を通過するようにマイクロ波の照射対象物３を移動させる移動部１３と、を備える。【選択図】図１
