There is provided an engine-start control technology that can prevent abnormal noises from occurring when controlling a starter system and malfunctions from occurring when an engine is started. The engine control device controls the startup of an engine in a vehicle by directing a current from a power source to a coil that causes an output shaft of a starter motor to engage with or disengage from the engine. The engine control device is provided with a delay unit which delays or cuts off a flow of current from a first current system, which directs current to the coil, to a second current system, which directs current to the starter motor. When a starter switch, which turns the flow of current from the power source to the first current system on or off, is turned on and electricity flows to the first current system, the delay unit delays the current flowing from the first current system to the second current system. When electricity flows to the first current system as a result of a controller having turned a first switch on, the delay unit cuts off the flow of electricity from the first current system to the second current system. This makes it possible to prevent abnormal noises from occurring when controlling the starter system and malfunctions from occurring when the engine is started.
