PROBLEM TO BE SOLVED: To provide a heating cooker achieving both high-efficiency heating and high reliability.SOLUTION: A heating cooker includes a heating chamber, a microwave oscillator generating a microwave supplied to the heating chamber, and a transmission path transmitting the microwave between the heating chamber and the microwave oscillator. A first coupling hole 83A and a second coupling hole 83B are formed to a wall surface of the transmission path. The heating cooker also includes: a branch path connected to the first coupling hole 83A and the second coupling hole 83B and longer than the distance between the first coupling hole 83A and the second coupling hole 83B; and a directional coupler 8 including the transmission path and the branch path.SELECTED DRAWING: Figure 3 【課題】高効率加熱と高信頼性を両立する加熱調理器を提供する。【解決手段】加熱室と、加熱室に供給するマイクロ波を発生するマイクロ波発振器と、加熱室とマイクロ波発振器の間にマイクロ波を伝送する伝送路と、を備え、伝送路の壁面に第一の結合孔８３Ａと第二の結合孔８３Ｂとが形成されており、第一の結合孔８３Ａと第二の結合孔８３Ｂとに接続されて、かつ第一の結合孔８３Ａと第二の結合孔８３Ｂとの間隔よりも長い分岐路と、伝送路と分岐路を含む方向性結合器８と、を備える。【選択図】図３
