An object is to shorten a time required for reprogramming of a control device including a single-bank microcomputer. An ECU 901 is a control device including a first microcomputer 1 and a second microcomputer 2 that execute a program stored in a rewriting area 13 in which a memory bank is configured as a single bank. The second microcomputer 2 includes a preprocessing unit 214 that performs preprocessing on a rewriting program 5 in reprogramming processing of rewriting the program stored in the rewriting area 13 into the rewriting program 5, and a transmission unit 213 that transmits the preprocessed rewriting program 5 to the first microcomputer 1. The first microcomputer 1 includes a reception unit 121 that receives the rewriting program 5 transmitted from the second microcomputer 2, and a writing unit 122 that writes the received rewriting program 5 in the rewriting area 13.
