The present invention provides an engine control device for an electric vehicle capable of simultaneously reducing the number of particles of particulate matter and reducing NV. An electric vehicle isprovided with: a rotating electric machine that generates a driving force for driving wheels; a power storage device that stores electric power supplied to the rotating electric machine; a power generator that generates power for charging the power storage device; and an engine that generates a driving force for driving the generator. The engine control device for the electric vehicle is providedwith an engine control unit, and the engine control unit determines the rotating speed and the torque of the engine and controls the engine. Thus, the number of particles of the particulate matter per unit amount of gas discharged from the engine to the atmosphere is equal to or less than a target value. When the vehicle speed is less than a threshold value, the engine speed is set to a lower speed than when the vehicle speed is greater than or equal to the threshold value, and the target value is a value set in accordance with a warm-up state of the engine, an engine speed, and an engine torque.
