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