PROBLEM TO BE SOLVED: To provide a capacitive load driving circuit for dealing with larger capacity of a load and higher speed of driving and reducing power consumption. SOLUTION: The capacitive load driving circuit drives load capacity by connecting a first reference potential point to the load capacity via a first switch S1, and a second reference potential point to the load capacity via a second switch S2. A third reference potential point having a potential between the potential of the first reference potential point and the potential of the second reference potential point is connected to one end of a resonance coil L via a third switch S3, a fourth reference potential point having a potential between the potential of the third reference potential point and the potential of the second reference potential point is connected to one end of the coil via a fourth switch S4, and the other end of the coil is connected to the load capacity CL.
