PROBLEM TO BE SOLVED: To enable phosphor to emit light with high luminance and have long life. SOLUTION: The cold cathode fluorescent lamp comprises a transformer TS of which secondary coil L2 has a middle point NP grounded; a first rectifier diode D1 of which anode is connected to one end of the secondary coil of the transformer TS; a second rectifier diode D2 of which cathode is connected to the other end of the secondary coil, wherein a pulse voltage is applied to the primary coil L1 of the transformer TS, positive differential pulse-like voltage induced on one end side of the secondary coil is applied to the anode 13 of the cold cathode fluorescent lamp 10 through the first rectifier diode D1 and negative differential pulse-like voltage induced on the other end side of the secondary coil is applied to the cathode 14 of the cold cathode fluorescent lamp 10 through the second rectifier diode D2.
