PROBLEM TO BE SOLVED: To suppress unevenness in luminance at the periphery of an operation button which is lit according to the operation state of equipment in electronic equipment. SOLUTION: Ribs 55e, 55f for guiding light are formed from LEDs 52, 53 to a light guide section 55c at a disk 55a of a light guiding member 55. Light emitted from the LEDs 52, 53 is transmitted through the ribs 55e, 55f for guiding light and reaches a non-irradiated region X, thus sufficiently applying light also to the non-irradiated region X that is shadowed by a light-shielding section 56a and allows the light-shielding section 56a to shield direct light from each LED, and suppressing unevenness in luminance at an emission section 55b without arranging LEDs separately near the light-shielding section 56a.
