An object of the present invention is to provide an illumination apparatus which includes an illumination fixture having an open-type reflector and a metal halide lamp, and can suppress a decrease in intensity and occurrence of glare. An illumination apparatus (10) of the present invention includes a metal halide lamp (14) and an illumination fixture (12). The metal halide lamp includes an arc tube (30) which has therein a pair of electrodes, an inner tube (32) which houses the arc tube and has a pinch seal part at one end, and an outer tube (34) which houses the inner tube and has a base at one end. The illumination fixture includes a reflector (16) having a concave reflecting surface (20), a socket, and an attachment (18). In the inner tube, a diffusing part (88) which diffuses light emitted from the arc tube is formed in an area closer to a lower end of the inner tube than a center between the pair of electrodes. |
