An electrodeless lighting system using microwaves and a resonator thereof are provided to prevent local heating of an electrodeless bulb by disposing the electrodeless bulb in a resonator in a direction of linear electric field. A microwave generator(121) generates microwaves. A resonator(130) is disposed on an output side of the microwave generator, and shields leakage of microwaves to form any one of TM_012, TM_013, TM_014 or TM_015 mode therein. A cylindrical electrodeless bulb(145) has a fluorescent material excited by the microwaves, and is disposed in the resonator. The resonator has a resonator body(131) having an opened side to shield the microwaves and light, and a shielding member(141) disposed in the opening of the resonator body for shielding leakage of microwaves while passing the light.
