PROBLEM TO BE SOLVED: To provide a lighted push-button device which has a simple base plate construction. SOLUTION: The lighted push-button device comprises a push switching member 1, a base plate 3 on which a light source 2 with a light emitting diode is installed, a push bottom 4 which is installed on a top of the push switching member 1, and a light guide D whose front portion 5 is disposed in front of the push button 4, whose bent portion 6 which is formed at an end portion of the light guide D has an end surface into which light from the light source 2 is guided and the guided light is emitted forward from the front portion 5. An end portion of the bent portion 6 of the light guide D is inserted into an inside of a light shielding cylinder 7 surrounding the light source 2. The light shielding cylinder 7 is preferably fixed on the base plate 3. It is preferable that metal film which reflects the guided light forward is evaporated on a rear surface of the front portion 5 or a reflecting surface consisting of many grooves, many ridges or many white dot printings is formed on the rear surface of the front portion 5.
