ABSTRACT:
A plurality of first light reflection parts20ain the form of a first V-shaped groove, for reflecting light entering from a first light source12aand a plurality of light reflection parts20bin the form of a second V-shaped groove, for reflecting light entering from a second light source12bare formed, an intersection angle θPof the planes of the first V-shaped groove and an intersection angle θPof the planes of the second V-shaped grooves are substantially equal to each other, the planes of said plurality of first light reflection parts and the planes of said plurality of second light reflection parts are tilted at respective angles at which the light exits in the direction substantially perpendicular to the longitudinal direction of the linear light conductor14, said plurality of first light reflection parts are formed in at least a region near the end of the linear light conductor, opposite to the end thereof near which the first light source is disposed, and said plurality of second reflection parts are formed in at least a region near the end of the linear light conductor opposite to the end thereof near which the second light source is disposed.
