PROBLEM TO BE SOLVED: To provide a self-luminous road stud which facilitates embedding installation work and is not easily damaged.SOLUTION: The self-luminous road stud includes a main body for radiating light emitted by an interior self-luminous part to the outside from a light radiation part provided on an upper surface, and a bottomed cylindrical outer frame in which the main body is detachably stored from the upper part, a blade part projected to the side is formed on the main body, a mounting part capable of mounting the blade part is formed on the upper surface of the outer frame, and the main body is stored inside the outer frame in the state of mounting the blade part of the main body on the mounting part of the outer frame. The main body is detached from the outer frame after being embedded and fixed in an installation location and maintenance and exchange are easily performed. Also, when external force is applied from the upper part by a wheel of a vehicle stepping on the installed self-luminous road stud or the like, the external force is received by the mounting part provided on the bottom cylindrical outer frame, and the outer frame and the main body are not easily destroyed by the external force.
