Claim 0:
1. A vehicular light guide member to guide light in one direction by a light guiding operation, comprising:
a main body part; and
at least one light entrance part provided on a side face of the main body part to cause the light to join the main body part,
the main body part having:
an exit surface provided at a side face opposite to the side face where the light entrance part is provided, and allowing part of internal light to be emitted outside as emitted light; and
a plurality of specular surfaces provided at the side face where the light entrance part is provided, facing the exit surface, and reflecting the internal light toward the exit surface as reflected light,

wherein some of the plurality of specular surfaces constitute a displaced section so formed as to be displaced to a position closer to the exit surface or a position farther from the exit surface with respect to a reference section constituted of remains of the plurality of specular surfaces,
wherein the displaced section is provided on a downstream side in a light guiding direction of the light entrance part, and
wherein the specular surfaces of the displaced section are displaced to positions closer to the exit surface, increase the reflected light as compared with the reflected light from the specular surfaces in a state before being displaced, and direct the reflected light toward a portion with a small luminance value of the exit surface.
