A light guiding member having a light direction changing face which extends in a longitudinal direction of the light guiding member and a light emitting face which faces the light guiding member, wherein the light direction changing face includes two faces arranged so that vertical faces which extend in the longitudinal direction and are respectively vertical to the two faces, intersect with each other. Also, a bifurcated linear light source apparatus comprises a LED, a light guiding member which is made up of a transparent rod shape member, and which emits light generated by the LED, in two directions, from a longitudinal direction side face of the transparent rod shape member, and a reflection mirror which reflects the light emitted in one of the two directions, to the other direction of the two directions.
