To provide an LED lighting device that can exchange an integrated electric element related to drive voltage conversion.

The LED lighting device includes an LED unit 4 arranged in a housing 3 and emitting light through a light transmission part of the housing 3 by being driven with DC voltage, and a drive unit 5 arranged in the housing 3 and converting AC input voltage from an external power source into DC voltage. The drive unit 5 includes a drive circuit 52 arranged on a circuit board 51 electrically connected with the LED unit 4 and creating DC voltage by being electrically connected with the LED unit 4, and an integrated electric element 53 made associated to voltage conversion, detachably connected with the circuit board 51 and exposed from an insertion hole of the housing 3.
