To reduce a workload and cost for detecting change in a state of an object.SOLUTION: A detection device includes: a sensor unit for emitting an electromagnetic wave or a sound wave to an object to be detected to receive the electromagnetic wave or the sound wave reflected by the object; a registration unit for registering information on a reference reception signal of the electromagnetic wave or the sound wave reflected by the object and received by the sensor unit as reference data when the object is in a normal state; and a detection unit for detecting change in a state of the object based on the reference data and a reflection signal that is the reception signal of the electromagnetic wave or sound wave reflected by the object.SELECTED DRAWING: Figure 1 【課題】対象物の状態の変化を検知するための作業負荷およびコストを低減する。【解決手段】検知装置は、検知対象である対象物に対して電磁波または音波を発射し、対象物で反射された電磁波または音波を受信するセンサ部と、対象物が正常状態である場合に、対象物で反射されてセンサ部が受信した電磁波または音波の基準受信信号の情報を、基準データとして登録する登録部と、基準データと、対象物で反射された電磁波または音波の受信信号である反射信号とに基づいて、対象物の状態が変化したことを検知する検知部と、を備える。【選択図】図１
