To provide an illuminated switch capable of reducing luminance variations of a light exit surface of a light guide member.

Parallel light R1 emitted from a second light guide member 30 is refracted in a first direction D1 when entering inside of the first light guide member 20 from a light incident surface 21 of the first light guide member 20. Light R3 being refracted propagates within a second light guide member 30 and is reflected by a reflection surface 23 provided on a bottom portion thereof. Light R4 being reflected propagates within the first light guide member 20 in a second direction D2 and reaches a light exit surface 22. Since light emitted from a light source is emitted after being once reflected by the reflection surface 23, the light can propagate to a periphery portion of the light exit surface 22, and, therefore, the luminance variations of the light exit surface 22 can be reduced.
