A light-emitting unit having a plurality of LED light sources (7a to 7d) and a planar lightguide (2) that guides light from the LED light sources (7a to 7d) and that emits the light from a light-exiting portion located on an outer periphery (2a). The planar lightguide (2) has a reflecting portion (2b) that reflects light from the LED light sources to emit the light to the outside from the light-exiting portion of the outer periphery (2a). The planar lightguide (2) also guides light from the LED light sources directly to the outer periphery (2a) to emit the light to the outside from the light-exiting portion.
