ることを特徴とする照明装置。[Claims for Utility Model Registration] Light from a light source is incident on one end surface of a light transmitting body made of a rod-shaped transparent member, and the incident light is diffusely reflected by a light diffusing portion formed on the circumferential surface of the light transmitting body. and a holder for supporting the light transmitting body while maintaining a predetermined positional relationship with the light diffusing part in the illumination device that emits diffusely reflected light from the peripheral surface of the light transmitting body to illuminate an illuminated object. The holder has a mounting part for attaching a light amount sensor for receiving a part of the light diffusely reflected by the light diffusing part and controlling the amount of light emitted from the light source, and a position of the object to be illuminated. A lighting device comprising: a positioning reference portion that determines a relationship.
