PROBLEM TO BE SOLVED: To make an indicator lighting and a character lighting possible to perform compatibly with simple composition while arranging keys continuously in small gaps. SOLUTION: A rubber key 24 equipped with a protrusion 28, is fixed with adhesion to a holding board 22 while forming a space 26 for switching between the holding board 22. A sheet switch 30 is fixed with adhesion fixation at the rubber key 24 so that a switch section 32 divided by two or more slits 31a in the position adjusted to the convex sections 28 of the rubber key 24 may contact directly. A key-top 34 in which an indicator lens 36 and a key space 37 for the character lighting are formed, is fixed with adhesion so that the key-top may be adjusted to the switch section 32 of the sheet switch 30. A light source 38 for indicating is attached in a part adjusted to the indicator lens 36 of the switch section 32 of the sheet switch 30. Further, a light source 40 for key lighting is attached in a position adjusted to the key space 37.
