An indicator lamp excellent in visibility not only from a near distance but also from a far distance and in viewing angle characteristics. An indicator lamp in which a light-emitting element (2) provided to a light-emitting element mounting section (3) formed at the bottom of a lens (1) for the light-emitting element emits light, and the emitted light is totally reflected from the peripheral wall (4) of the lens (1) and projected forward. The peripheral wall of the lens body includes circumferential angular portions (7, 8) which are boundaries formed by stepwise decreasing the angle to the center axis of the lens body from the bottom to the lens front surface (5), and the circumferential angular portions forward scatter the light emitted from the light-emitting element (2) and project concentrically the light when viewed from the front of the lens. |
