The messages include a periodic message and an event message. The in-vehicle device includes: a creation unit configured to create the periodic message and the event message; and a transmission control unit configured to transmit the periodic message and the event message created by the creation unit. In transmitting the event message, after a waiting time elapses from a transmission timing of a previously transmitted message among the messages to which the identification information of the same value as that of the event message to be transmitted is added, the transmission control unit transmits the event message to which the identification information of the same value is added. The waiting time is longer than half a transmission cycle of the periodic message and is shorter than the transmission cycle.",
