Abstract
An illumination device () includes: a plurality of LEDs () that are the light sources, the LEDs being arranged in a row in a circular shape; and a diffusion lens () disposed on the light-emitting side of the LEDs () in order to diffuse light emitted by the LEDs (), the diffusion lens () being disposed so as to follow an arrangement direction of the LEDs () to cover these LEDs. The degree of light diffusion of the diffusion lens () towards the direction forming a right angle with the arrangement direction of the plurality of LEDs () is larger than the degree of light diffusion towards the arrangement direction of the plurality of LEDs ().
