A purpose of the present invention is to obtain a failure predictor detection device that more accurately detects a predictor of a failure. A failure predictor detection device according to the present invention comprises: an acquisition unit that acquires estimation data and comparison data when detecting a failure detector in an instrument that is the target of failure detector detection; an estimation unit that uses a learning model to calculate, based on the estimation data, an estimation value for the comparison data during normal operation; and a detection unit that detects the failure detector for the instrument on the basis of the result of comparison at multiple times of the estimation value with an actual measurement value indicated by the comparison data.
