Zusammenfassung:	To provide a state determination device and state determination method capable of determining a state of a device having a moving body changing a flow of a fluid with higher accuracy.SOLUTION: A state determination device includes a first calculation section, a second calculation section, and a state determination section. The first calculation section calculates a first feature quantity related to operation energy to a moving body changing a flow of a fluid in a flow passage. The second calculation section calculates a second feature quantity related to pressure of the fluid. The state determination section determines a state in the flow passage on the basis of the second feature quantity when the first feature quantity is within a predetermined range.SELECTED DRAWING: Figure 1 【課題】流体の流れを変える運動体を有する装置の状態判定をより高精度に判定可能な状態判定装置、及び状態判定方法を提供する。【解決手段】本実施形態に係る状態判定装置は、第１演算部と、第２演算部と、状態判定部と、を備える。第１演算部は、流路内における流体の流れを変える運動体への動作エネルギーに関連する第１特徴量を演算する。第２演算部は、流体の圧力に関する第２特徴量を演算する。状態判定部は、第１特徴量が所定範囲内である場合に、第２特徴量に基づき流路内の状態を判定する。【選択図】図１
