PROBLEM TO BE SOLVED: To provide a light guide lens achieving higher flexibility of design by increasing the quantity of light to be transmitted ahead of a curved area. SOLUTION: The light guide lens is arranged in a region deviating from the optical path of light emitted from the light source of a vehicular headlight and distributed as predetermined. The light guide lens includes a lens body part along the vertical direction, a curved part curved relative to the lens body part to be apart from the optical axis of the light source, and an extending part extending from the front end of the curved part approximately perpendicular to the extending direction of the lens body part. The lens body part has an entrance surface into which light deviating from the optical path enters, and a reflecting surface from which the light entering from the entrance surface is internally reflected toward the curved part. On the outer peripheral face of the curved part, a cut surface is formed to internally reflect the light reflected from the reflecting surface toward the extending part.
