PROBLEM TO BE SOLVED: To provide an illumination device capable of reducing manufacturing man-hour in fixing a substrate on which an LED is placed.SOLUTION: An LED illumination device has: an LED; a wiring substrate on which the LED is placed; a heat radiating plate including a wiring substrate placing part on which the wiring substrate is placed; a backbone for fixing the heat radiating plate; a power supply substrate mounted on the backbone via an insulating plate and controlling the LED; and a cover shade upper mounted on the backbone so as to cover a side surface from a back surface of the backbone; and a cover shade lower mounted on the cover shade upper and covering a front surface of the LED. The wiring substrate is a flat plate component and it comprises: a circular part on which the LED is placed; and a wiring substrate protrusion provided on an outer periphery of the circular part. A substrate presser which locks the wiring substrate protrusion by rotation of the wiring substrate in the circumferential direction is provided on the outer periphery side of the wiring substrate placing part. |
