An electronic control apparatus that controls actuation of an inductive load includes: a current detector that detect current flowing through the inductive load and outputs a current detection signal in an analog signal; an analog-digital converter that takes in the current detection signal at a fetch timing, and converts the current detection signal into a current detection value; and a controller that calculates a current arithmetic value by executing arithmetic processing for the current detection value, and controls the current based on the current arithmetic value. The controller obtains a sample data value of the current arithmetic value for each of a plurality of fetch timings. The controller calculates a deflection between an ideal value of the current arithmetic value and the sample data value of the current arithmetic value, and learns the fetch timing, causing the deflection with the ideal value of the current arithmetic value to be minimized.
