A plasma display panel drive apparatus that executes a gradation display by having an address period in which light-emitting cells are set, and a sustain period in which the light-emitting cells that were set in the address period are repeatedly lit up, is provided with: a pulse-output device which outputs a drive pulse to the plasma display panel during the sustain period; a first intensity-level-detection device which detects the average intensity level; a second intensity-level-detection device which detects the intensity level of each discharge cell; and a pulse-voltage-control device which controls the pulse-output device such that the drive-pulse voltage changes based on the average intensity level detected by the first intensity-level-detection device, and the intensity level of each the discharge cell that was detected by the second intensity-level-detection device.
