PROBLEM TO BE SOLVED: To make light-emitting state in a light-emitting window of a lens holder to be a perfectly continuous annular emission ring, with respect to an illuminated push-button unit in which a light-emitting face is displaced following the pushing operation of a pushing operation part. SOLUTION: The illuminated push-button unit is provided with a light guide lens 10 to guide the light from a light source to a circular light-emitting face 11 to emit light, a lens holder 50 having a circular light-emitting window 53, and a pushing operation part 20 arranged at the center of the light-emitting window 53. The pushing operation part is integrated into the light guide lens 10 and protruded from the center of the light-emitting face 11, thereby the light-emitting face 11 of the light guide lens 10 is formed in ring-shape at the surrounding of the pushing operation part 20.
