[Object] To provide an LED lighting device capable of suppressing a flicker at an intermediate level in which a dimming level is moved between a high level and a low level. [Means for Settlement] The LED lighting device includes a constant current output part 21 capable of variably adjusting an amplitude for supplying a constant current I1 with a fixed amplitude to an LED light-emitting part 4, and a PWM current output part 22 for variably adjusting an on-duty state in a PWM cycle by PWM control and supplying a PWM current with a predetermined on-duty state to the LED light-emitting part 4, wherein in an intermediate dimming range, the constant current output part 21 adjusts the amplitude of the constant current I1 in accordance with a dimming level and the PWM current output part 22 adjusts the on-duty state of the PWM current in accordance with the dimming level, so that the LED light-emitting part 4 is dimmed.
