Imaging lens and electronic device

The utility model discloses an imaging lens. The imaging lens comprises an anti-dazzling screen. The light shielding sheet comprises an object side surface, an image side surface, an inner ring surface, a plurality of tapered light shielding structures and a nano-structure layer. The object side is perpendicular and surrounds the optical axis. The image side surface is opposite to the object side surface, and the image side surface is closer to the image side than the object side surface. The inner ring surface is connected with the object side surface and the image side surface, surrounds the optical axis and defines a light through hole. The gradually-shrinking shading structure is arranged on the inner ring surface and gradually shrinks and extends towards the optical axis, and the gradually-shrinking shading structure is periodically arranged around the optical axis. When observed in the direction of the optical axis, the contour of each gradually-shrunk shading structure is provided with a curve segment.
