To provide a technique for improving the reliability of a Rankine cycle device provided with a reheater.SOLUTION: A Rankine cycle device 50 includes a main flow path F1, a first bypass flow path F2, and a temperature sensor 10. The main flow path F1 has a pump 1, a first portion 2a, an evaporator 3, an expander 4, a second portion 2b, and a condenser 5, in which a working fluid flows through these elements in this order. The main flow path F1 is provided with a reheater 2 which has the first portion 2a and the second portion 2b. The first bypass flow path F2 connects a portion which is downstream of the pump 1 and upstream of the first portion 2a in the main flow path F1 to a portion which is downstream of the first portion 2a and upstream of the evaporator 3 in the main flow path F1. The first bypass flow path F2 has a first valve 7. The temperature sensor 10 detects the temperature of the working fluid in at least one selected from the group consisting of an inlet of the evaporator 3, an inside of the evaporator 3, and an outlet of the evaporator 3.SELECTED DRAWING: Figure 1 【課題】再熱器を備えたランキンサイクル装置の信頼性を向上させるための技術を提供する。【解決手段】ランキンサイクル装置５０は、主流路Ｆ１、第１バイパス流路Ｆ２、および温度センサ１０を備える。主流路Ｆ１は、ポンプ１、第１部分２ａ、蒸発器３、膨張機４、第２部分２ｂおよび凝縮器５を有し、作動流体がこれらの要素をこの順番で流れる。主流路Ｆ１には、第１部分２ａと第２部分２ｂとを有する再熱器２が設けられている。第１バイパス流路Ｆ２は、主流路Ｆ１におけるポンプ１よりも下流側かつ第１部分２ａよりも上流側の部分と、主流路Ｆ１における第１部分２ａよりも下流側かつ蒸発器３よりも上流側の部分とを接続している。第１バイパス流路Ｆ２は、第１弁７を有している。温度センサ１０は、蒸発器３の入口、蒸発器３の内部および蒸発器３の出口からなる群より選ばれる少なくとも１つにおける作動流体の温度を検出する。【選択図】図１
