Abstract
Provided is an illumination lens, including: a lens portion provided in a substantially central portion of a plate surface of a plate-like member; a flat portion provided in a region other than a region of the lens portion of the plate surface; and a reflection suppression structure configured to suppress total reflection of light inside, the reflection suppression structure being provided in at least one of the flat portion and a side end portion. The illumination lens enables emitting light having a more favorable characteristic with a simpler configuration.
