In an inductive load driving system, it is configured to comprise a first switching element that is inserted in a position between the external power supply and the inductive load, a second switching element that is inserted in a position between the inductive load and the ground, a return current circuit including a first branch path which diverges at a location between the first switching element and the inductive load to be connected to the ground, that returns counter electromotive current to the ground when the second switching element is turned on, and a counter electromotive current reduction circuit including a second branch path which diverges at a location between the inductive load and the second switching element to be connected to the external power supply, that reduces the counter electromotive current to the external power supply when the first and second switching elements are turned off.
