An optical member includes a light guide body that includes a smooth incident surface, a reflecting and emitting surface disposed to face the smooth incident surface, a reflecting surface continuously arranged with the smooth incident surface, and a smooth emitting surface continuously arranged with the reflecting and emitting surface. The reflecting and emitting surface includes first flat portions configured to emit a part of an incident light, and first reflecting portions configured to reflect another part of the incident light. The reflecting surface includes second flat portions and second reflecting portions configured to reflect the light reflected by the first reflecting portions in different directions toward the smooth emitting surface. The smooth emitting surface is configured to reflect the light reflected by the second flat portions by total reflection and emit the light reflected by the second reflecting portions to the outside.
