An anomaly detection device (110a) is located between a bus (130) and an ECU (101a), and includes: a communication section (111) that receives a message from the ECU (101a) and transmits the message to the bus (130), and receives a message from the bus (130) and transmits the message to the ECU (101a); a received ID list holder (114) that holds a received ID list which is a list of IDs of messages that the communication section (111) has received from the bus (130) and transmitted to the ECU (101a); and a controller (112), wherein the controller (112): in the case where an ID of the message received by the communication section (111) from the bus (130) is not included in the received ID list, adds the ID to the received ID list; and in the case where an ID of the message received by the communication section (111) from the ECU (101a) is included in the received ID list, causes the communication section not to transmit the message to the bus (130).
