Zusammenfassung:	A printed circuit board of an engine control unit is provided to prevent erroneous operation of each unit for performing engine control, by permitting influence of noise generated during ignition signal processing to exist only in the relevant ground region. A printed circuit board of an engine control unit includes a first region(410) and a second region(420) having mutually independent ground fields. An ignition driver region(411) for receiving an ignition signal generated firstly from the inside of an engine control unit(400) and transmitting the ignition signal to a spark coil arranged outside the printed circuit board, is routed in at least one of the first region and the second region.
