An anomaly detection device included in a communication network adopting a time-triggered protocol based on a time slot includes: a frame transceiver (201) that receives frames; and an anomaly detector (252) that detects an occurrence of an anomalous frame in accordance with a time slot among a plurality of time slots included in a cycle and the number of repeated cycles of the cycle for each frame. The anomaly detector (252) detects an occurrence of an anomalous frame by verifying a statistic on the frames received while the cycle is repeated a predetermined number of times, which is at least once, against a rule indicating a reference range of the statistic.
