Abstract
A light guide member includes a main body part, and an entrance surface, a strip-shaped exit surface and a strip-shaped reflecting surface that are formed on the main body part. The illumination light is output from the exit surface. The reflecting surface extends in the first direction on a face placed opposite to the exit surface of the main body part and reflects the illumination light. The reflecting surface includes, on a flat face, a reflection pattern surface provided with a plurality of minute reflective concave parts having a function of reflecting the illumination light toward the exit surface. The reflective concave parts each include a deflection surface which deflects the illumination light in a direction in which a reflection angle widens in a cross sectional view in a second direction that is orthogonal to the first direction in a horizontal direction, and then reflects the illumination light.
