The light shielding portion is provided on a surface of the light guide or at a position away from the light guide so as to block an outside light entering the light guide. The light shielding portion has a first light shielding portion for blocking light incident on an inclined surface and a second light shielding portion for blocking light incident on the flat portion in a predetermined direction.
