A lighting device including a plurality of dielectric barrier discharge lamps is provided to authentically perform an error detection of a lamp by lighting a plurality of lamps in one lighting device. A lighting device including a plurality of dielectric barrier discharge lamps comprises the followings: a lighting circuit(3) generating a high frequency voltage; a plurality of dielectric barrier discharge lamps(2) parallely connected to the lighting circuit; a current detection circuit(4) detecting a value of a lamp current flowing into the dielectric barrier discharge lamps; and an error detection circuit determining an error in a plurality of dielectric barrier discharge lamps. |
