Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an illuminating device capable of obtaining a desired curved-shape illumination pattern with a small number of light sources. SOLUTION: The illuminating device, equipped with at least one LED (light source) 1 and at least one lens 3 transmitting light emitted from the LED 1, obtains the curved-shape illumination pattern P1 by a plurality of cuts applied on the lens 3. With a position point-symmetric to the center O1 of the LED 1 about the center of curvature of a center line CL in the curved-shape illumination pattern P1 as a reference point A in viewing from a light-irradiated direction, a plurality of straight-line cuts radially extended from the reference point A are applied to the lens 3, whereby, the curved-shape illumination pattern P1 is obtained as one emitting light around the curved line connecting intersection points where the straight line cuts cross perpendicularly with a plurality of the optical rays C1 radially extended from the center of the LED 1.
