    Abstract: Provided is an abnormality detection apparatus and the like capable of quickly and accurately detecting lifting abnormality of a substrate attributable to detachment failure of a substrate from an electrostatic chuck, or the like. An abnormality detection apparatus 100 includes a measurement section 2 configured to measure a parameter having a correlation with load applied to a lifting mechanism 4; and a detection section 3 configured to detect lifting abnormality of a substrate S. The detection section 3 includes a learning model 31 generated by using machine learning, in which the learning model 31 receives, as input, a plurality of measurements of the parameter continuously measured by the measurement section 2 during lifting-up of the substrate S by the lifting mechanism 4, and outputs a level of lifting abnormality of the substrate S.
