Abstract
An optical lens including a light-shielding sheet and a spacer sequentially arranged along an optical axis from a first side to a second side is provided. No other element is disposed between the light-shielding sheet and the spacer. A second side surface of the light-shielding sheet includes a first surface. A first side surface of the spacer includes an abutting surface and a connecting surface connected to each other, and the connecting surface has a protrusion portion. A cross-sectional line of the abutting surface of the spacer in a radial direction is a straight line and abuts against the first surface of the light-shielding sheet, and an abutment between the abutting surface and the first surface falls on a first reference plane. The light-shielding sheet and a most protruding portion of the protrusion portion are located on a same side of the first reference plane.
