Abstract

To restrain increase in tube temperature of an electric discharge tube when increasing tube current or the number of discharge tubes of a cold cathode fluorescence discharge lamp apparatus. This cold cathode fluorescence lamp apparatus is provided with a holder (1) formed with a material of high heat radiation ability, a discharge tube (2) having both ends (3) supported by the holder (1), and a thermal-conductive bracket (5) fixed to a middle part (4) extending between the discharge tube (2) and both the end parts (3) and closely attached to the holder (1). Heat generated from the discharge tube (2) is discharged outside through the bracket (5) and the holder (1) thermally connected to the bracket (5) to prevent temperature increase of the discharge tube (2).
