The present invention provides a program rewriting device and a program rewriting method capable of easily rewriting a program. A rewriting control unit of a program rewriting device compares the current version information that is read from all rewritable ECUs included in a network with the latest version information corresponding to the current version information and extracts, as target ECUs, rewriting candidate ECUs in which the current version information does not match the latest version information. The rewriting control unit sequentially performs a program rewriting action for the extracted target ECUs in order of priority stored in an order DB.
