PROBLEM TO BE SOLVED: To provide an LED lighting device which can be mounted with simple work without adding construction such as drilling and the like to a mounted part such as a ceiling surface and the like, which can radiate heat of heat generation of the LED and the like efficiently, and also in which an LED element and electronic components can be arranged separately on one substrate, in which the number of components is reduced, whose configuration is simple and which can be manufactured at low cost.SOLUTION: An LED lighting device includes: an LED lamp body 1 in which an LED unit substrate is accommodated; and a mounting plate 2 having an insertion hole for an external power source cable and mounting the LED lamp body to a mounted part. The LED unit substrate 30 has a mounting surface for an LED element and a mounting surface for electronic components configuring a lightning circuit for lighting the LED element on one substrate, and the electric component mounting surface is formed by protruding to the outside part of the LED element mounting surface. The LED unit substrate 30 has a substantially disc shape in which a notch part is formed at one part of a peripheral edge part. |
