Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an illumination device which, as one having a main light source and a secondary light source, has illumination performance effect related to a sense of spatial openness, a sense of depth, and a sense of brightness, is capable of achieving a prescribed illuminance distribution, and is superior in design and luminous efficiency.SOLUTION: The illumination device 1100 includes: a cylindrical cabinet 110 having a first light-emitting part 100 (main light-emitting part); and a second light-emitting part 200 (secondary light-emitting part) which is supported at a position of a pivotal tip cabinet 210 by several pivots 300 stretched from a side face of the cylindrical cabinet 110 and emits light with different light distribution characteristics from those of the first light-emitting part 100. The second light-emitting part 200 has an annular form supported by the tips of the pivots 300. LEDs are used as a second light source part in the second light-emitting part 200 which has a light guide body 230. The light guide body 230 propagates light of the second light source part arranged at the tips of the plurality of pivots 300 to emit the light to a space.
