PROBLEM TO BE SOLVED: To provide an electronic control device capable of restraining the occurrence of wiring restriction and an unusable terminal even in a configuration in which microcomputers are arranged as close to each other as possible and connection among data communication terminals of the respective microcomputers is performed according to equal length wiring.SOLUTION: In an electronic control device 100, microcomputers 101, 102 each comprise a communication terminal section 104 including a plurality of data communication terminals at a corner of the respective microcomputers. The communication terminal section includes a transmission terminal group area 105 including a plurality of transmission terminals, and a reception terminal group area 106 including a plurality of reception terminals. The transmission terminal group area and the reception terminal group area are arranged next to each other and arranged so that distance between the transmission terminal of one microcomputer and the reception terminal of another microcomputer corresponding to the one transmission terminal equals to distance between the transmission terminal of another microcomputer and the reception terminal of the one microcomputer corresponding to the other transmission terminal. |
