PROBLEM TO BE SOLVED: To provide an electronic control unit for providing improved work efficiency and quality, and having such arrangement that electronic substrate size is not increased by mounting a high density electronic part and an atmospheric pressure sensor on an identical electronic substrate, executing a damping-proof coating process for the high density electronic part, and preventing the damping-proof material from entering the atmospheric pressure sensor. SOLUTION: The electronic control unit in which the electronic substrate with the atmospheric pressure sensor is housed in a casing, and an outside air ventilation hole is provided at the casing includes: a second range and first range formed by dividing a first face and a second face formed on the electronic substrate into two of a side close to a connector housing and a side far from that for connecting pin groups; and a locator correcting and aligning mounting parts loaded on the first face and/or the second face of the first range, and a plurality of the connecting pin groups. The first range is coated with the damping-proof material, with the second range in which the atmospheric pressure sensor is arranged not to be coated. COPYRIGHT: (C)2011,JPO&INPIT
