A plasma display apparatus ( 10 ) is provided with: a control device 100 ; a PDP 900 including a display panel device 200 and a driving device 400 ; and a functional device 500 . In operation of the PDP 900 , an X driving device 420 and a Y driving device 430 of the driving device 400 are drive-controlled by the control device 100 , and sustain pulse voltages are applied to sustain electrodes 213 of the display panel device 200 . This generates unnecessary radiant electromagnetic wave near the display panel device 200 and the driving device 400 . A coil 610 of a power regenerating apparatus 600 is provided such that the core direction of an air core portion 611 b is perpendicular to the radiant direction of the unnecessary radiant electromagnetic wave, and the coil converts the unnecessary radiant electromagnetic wave to an AC voltage. The AC voltage is converted to a DC voltage by a rectifying device 620 and it is regenerated as DC power for the functional device 500 through a power supply line.
