PROBLEM TO BE SOLVED: To provide a lighting device which can be decreased in number of light emitting element in use and improved in flexibility of an arrangement of the light emitting elements. SOLUTION: A diffusion section 12 is disposed around a knob 4 fitted to an operation shaft 8d of a rotary encoder 8 fitted to one surface of a substrate 6. An LED 18 is provided on the substrate 6 apart from the rotary encoder 8. A light guide section 14 formed integrally with the diffusion section 12 guides light emitted by the LED 18 to the diffusion section 12. COPYRIGHT: (C)2009,JPO&INPIT
