The plurality of communication units are configured to perform data transmission and reception and to transition between a plurality of states including a transmission enabled state and a transmission disabled state, and are respectively provided for the plurality of buses. The state control unit is configured to cause, after the elapse, following the occurrence of a preset event, of a relay transition time obtained by adding a preset additional time to a node transition time, the state of a specific communication unit representing a communication unit among the plurality of communication units that performs transmission and reception via a bus to which a specific node is connected, to transition from the transmission enabled state to the transmission disabled state.
