An anomaly detection device (100) includes: an obtainer (1001) that obtains vehicle information related to the status of a vehicle (30) and including location data indicating the location of the vehicle (30); a model storage (1002) that stores, for each of a plurality of cells of a grid imposed on a map, an evaluation model for evaluating the vehicle information of the vehicle (30) located at the cell; and a determiner (1003) that calculates, based on the vehicle information and evaluation models each being the evaluation model and corresponding to evaluation cells including a first cell including the location of the vehicle (30) indicated in the location data and one or more second cells each having a predetermined positional relationship with the first cell, an anomaly level indicating a degree of anomaly of the vehicle information, determines, based on the anomaly level, whether the vehicle information is anomalous, and outputs a determination result.
