One embodiment of the present invention provides an apparatus, or the like, which detects an anomaly of a controller of a control system by learning relationship between input and output of the controller. An anomaly detection apparatus which is one embodiment of the present invention includes a first acquirer, a second acquirer, a history recorder, an estimator, and a first anomaly determiner. The first acquirer acquires an input signal to a control apparatus which executes control on a controlled apparatus. The second acquirer acquires an output signal from the control apparatus. The history recorder records information regarding the acquired input signal and the acquired output signal as history. The estimator estimates the output signal using the history and an estimation model. The first anomaly determiner determines an anomaly of the control apparatus by comparing the estimated output signal with the acquired output signal.
