    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.

    Abstract: Alighting device includes an optical fiber having a first end portion from which a light emitted by a light source is introduced, and a second end portion, the optical fiber allowing the light to pass therethrough while radiating from a side surface of the optical fiber to an outside; a tube having light-transmissivity and covering the side surface of the optical fiber, such that a gap is located between the side surface of the optical fiber and the tube; a light-shielding cylindrical body covering the second end portion of the optical fiber, such that a space is located between the second end portion of the optical fiber and the cylindrical body, at least a portion of the light-shielding cylindrical body being disposed in the tube; and a light conductive part on a side surface of the cylindrical body, the light conductive part allowing light radiated from the second end portion of the optical fiber to be conducted to a portion of the tube at an outside of the cylindrical body in a diametrical direction of the cylindrical body.
