A light guide member (52,52A) which is used by being combined with a light source that emits an illumination light, comprising: a main body part which has a long rod shape in a first direction and guides the illumination light; an entrance surface which is one end face of the main body part and through which the illumination light enters; a strip-shaped exit surface which extends in the first direction on a surface of the main body part and from which the illumination light is output; and a strip-shaped reflecting surface which extends in the first direction on a face of the main body part, the face being placed opposite to the exit surface, and which reflects the illumination light; wherein 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, and 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 reflects the illumination light, characterized in that the reflection pattern surface is formed in a first region near the entrance surface of the main body part, and another reflection pattern surface including a pattern formed from a plurality of arrays of V-shaped prism configured from a V-shaped concave groove extending in the second direction is formed in a second region of the reflecting surface, said region being farther from the light source than the first region. a main body part which has a long rod shape in a first direction and guides the illumination light; an entrance surface which is one end face of the main body part and through which the illumination light enters; a strip-shaped exit surface which extends in the first direction on a surface of the main body part and from which the illumination light is output; and a strip-shaped reflecting surface which extends in the first direction on a face of the main body part, the face being placed opposite to the exit surface, and which reflects the illumination light; wherein 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, and 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 reflects the illumination light, characterized in that the reflection pattern surface is formed in a first region near the entrance surface of the main body part, and another reflection pattern surface including a pattern formed from a plurality of arrays of V-shaped prism configured from a V-shaped concave groove extending in the second direction is formed in a second region of the reflecting surface, said region being farther from the light source than the first region.
