Abstract: A transmission device has a detector, a generator, and a transmitter. When the detector has detected that a communication rule of a message that has been broadcasted to a network by another transmission device coincides with a communication rule of a message that is broadcasted to the network by the present transmission device, the generator generates an abnormality notification message. Then, the transmitter broadcasts an abnormality notification message to the network.
