A data analysis apparatus includes: a data obtainer (210) that obtains a plurality of anomaly analysis results each including information identifying anomaly data of first and second vehicles provided with an in-vehicle network (100) including one or more buses; and a relevant Electronic Control Unit (ECU) identifier (250) that (i) identifies, for each of the first and second vehicles, a primary ECU having higher relevance to the anomaly data among ECUs connected to the in-vehicle network (100), that (ii) identifies, for each of the first and second vehicles, ECUs connected to a bus in the one or more buses to which the primary ECU is connected as a secondary ECU set, and that (iii) identifies an ECU included in both of the secondary ECU set identified for the first vehicle and the secondary ECU set identified for the second vehicle and satisfying one or more predetermined conditions as an anomaly-relevant ECU.
