PROBLEM TO BE SOLVED: To suppress leak current by lessening floating capacity between a fluorescent lamp 4 and a fixture 2 in order to prevent other electronic equipment from noise obstacles caused by high-frequency leak current flowing into the ground through the fixture installed from an electronic ballast lit in high frequency and the fluorescent lamp. SOLUTION: The lighting fixture, provided with a metal-made fixture body 2 incorporating the electronic ballast, is to be of a double structure in which a non-metallic auxiliary reflecting plate 3 is mounted between the fixture body 2 and the fluorescent lamp 4 with a distance secured from the fixture body 2. Furthermore, a mounting position of the electronic ballast 1 is arranged in the vicinity of a lamp socket 5 corresponding to a high-pressure side of the electronic ballast 1 to shorten a high-frequency high-voltage electric path line.
