Abstract
An illumination device includes: an optical fiber, the optical fiber allowing light emitted from a light source to be introduced at a first end portion thereof and to be guided through the optical fiber while emitting a portion of the light through a side surface of the optical fiber; a light-transmissive tube, the light-transmissive tube covering the side surface of the optical fiber such that a gap is located between the tube and the side surface of the optical fiber; and a light-shielding cap covering a second end portion of the tube at a side opposite the light source such that a space is located between a bottom portion of the cap and the second end portion of the tube. A second end portion of the optical fiber projects past the second end portion of the tube and is located at an inner side of the cap.
