PROBLEM TO BE SOLVED: To provide a throttle valve control device capable of surely inhibiting opening stagnation at a default opening degree. SOLUTION: The throttle valve control device 1 comprises a control means 11 for controlling an opening degree of a throttle valve based on a control signal and a positioning means for positioning the throttle valve 14 so that a load step is caused on a drive shaft 15 of the throttle valve 14 at the default opening degree. The throttle valve control device comprises a target opening degree calculating means 30 for calculating a target opening degree of the throttle valve 14, a response value calculating means B30 for calculating an opening degree response value and an electric current response value having predetermined response delays based on the target opening degree, an electric current value calculating means B60 for calculating an electric current correction value for correcting operation near the default opening degree of the throttle valve 14 based on the opening degree response value, and a control signal calculating means 23 for calculating the control signal from the electric current response value and the electric current correction value.
