An on-board update device includes: an update information acquisition unit which acquires data from a device outside a vehicle. A prohibition processing unit prohibits communication between each of the communication devices to be updated and any other communication device. An update information transmission unit transmits the data acquired by the update information acquisition unit, via one or more in-vehicle communication units to the corresponding communication devices to be updated, after the prohibition processing unit has prohibited communication; a completion decision unit decides whether each of the communication devices to be updated has completed an update of the program or data; and a prohibition cancelling unit cancels the prohibition of communication between each of the communication devices to be updated and any other communication device, if the completion decision unit decides that all of the communication devices to be updated have completed their updates.
