PROBLEM TO BE SOLVED: To provide an outdoor lamp which prevents heat generated by LED elements from being transmitted to electronic components forming a lighting circuit to thereby prevent deterioration of the electronic components and efficiently radiates heat generated by the LED elements to outside the lighting device.SOLUTION: In an LED lighting device 100, an LED lamp body 10 housing an LED substrate 2 on which LED elements 1 are mounted and a lighting circuit board 5 is attached to target object by heat conductive attachment means 20. In the LED lighting device 100, one end side of the attachment means 20 is inserted into the LED lamp body 10. The LED substrate 2 is joined to the one end side of the attachment means 20 so as to conduct heat, and the lighting circuit board 5 is disposed spaced apart from the attachment means 20. |
