A program delivery center is a program update device which updates a program of an ECU mounted in a vehicle, wherein a right holder specification unit specifies a right holder who has a right to execute the update of the program on the basis of information regarding the vehicle, and a reprogramming guide execution unit sets and outputs program update guide notification to the right holder. Accordingly, the update of the program by a person other than the right holder can be avoided, thereby improving security. Furthermore, since the update of the program is notified to the right holder which can execute the update of the program, a program update execution frequency increases compared to a case where a user who cannot execute the update of the program is notified, thereby prompting the execution of the program update.
