摘要
An optical lens has an optical function portion having an optical function, and a flange portion formed around the optical function portion. The flange portion has a cut section, which is formed by cutting a gate portion, on a side surface thereof. In a case where the following are viewed from a direction of the optical axis of the optical lens, a concave portion is provided in at least a portion of a region in which the flange portion overlaps with a region obtained by straight lines connecting together an optical axis center of the optical lens and both ends of the cut section, and the concave portion is provided on both surfaces of the flange portion.
