A light emitting golf ball in which the ball body has a plurality of substantially hemispherical first cavities formed inwardly from the surface of a core, second cavities having a diameter smaller than that of the first cavities and provided from the bottoms of the first cavities toward the center of the core, thin through holes opened from the second cavities to the opposite side of the core, and a transparent cover layer formed on the surface of the core, characterized in that the tubular portion of a chemical light emitting body made of a hermetically sealed container of a flexible transparent material consisting of a tubular portion and a swelled light emitting portion having a diameter larger than that of the tubular portion is inserted tightly into the second cavity and the light emitting portion is fitted in the first cavity. Since the emission luminance is enhanced as compared with a conventional light emitting golf ball, the golf ball can be confirmed visually even from a remote place and can be used as many times as desired by replacing the chemical light emitting body. Furthermore, flight performance is not impaired because balance of the ball is sustained.
