To provide a steering controller capable of changing a drive force of an electric motor according to a behavior of a vehicle.SOLUTION: A steering controller includes a basic designation unit that designates a basic control value which serves as a basis of a control value of an electric motor, using a steering torque detected by a torque sensor, a correction unit that calculates a correction value using a vehicle behavior related value which relates to the steering torque and a behavior of a vehicle, and a predefined relationship between the steering torque and the vehicle behavior related value, and a final designation unit that designates the control value using the basic control value and the correction value. The correction unit includes a torque computation unit that computes an ideal torque which is an ideal steering torque, using the acquired vehicle behavior related value and the relationship, a deviation calculation unit that calculates a deviation of the steering torque from the ideal torque computed by the torque computation unit, and a correction value calculation unit that calculates the correction value using the deviation calculated by the deviation calculation unit.SELECTED DRAWING: Figure 3
