To provide an LED lighting device capable of suppressing costs of materials at low range, having high freedom of design, and also capable of being made thin.
The LED lighting device 1 is provided with a base body 3, a plurality of LED light sources 2a, 2b mounted on the base body 3, and a plurality of circular, elliptical or polygonal ringed reflective thin bands 4 of different sizes arranged slantwise from the base body 3. The plurality of reflective thin bands 4 are coaxially arranged on the base body 3, and each of the reflective thin bands 4, when viewed from a countering side of the base body 3, are formed as a circular, elliptical or polygonal rings with a predetermined width between a peripheral edge of a starting point where the reflecting thin bands 4 and the base body 3 are in contact with each other, and a peripheral edge at an end of the reflecting thin bands 4. The LED light sources 2a, 2b are each arranged outside of the peripheral edge of the starting point of each reflective thin band 4.
