To provide a lighting fixture of which designing for realization of lowering of temperature can be easily made through prevention of temperature rise of a lamp-lighting unit by radiation heat of an electrodeless discharge lamp and improvement of outward heat radiation effect of the electrodeless discharge lamp, for one using an electrodeless discharge lamp structured by combining a storage case containing a lamp lighting unit with the top part of a lamp-supporting member equipped with a radiating plate with a reflection hood mounted.

A heat radiating hole each 18a, 18b is set on the top and bottom part of a storage case 18 storing a lamp lighting unit 16, and at the same time, a shielding plate 15 is arranged between a reflection hood 12 fixed to a lamp supporting member 14 and the storage case 18.
