The imaging lens 10 provided by the embodiment of the present application includes a light transmissive member 100 and a light blocking sheet 200. The light transmission assembly 100 is a combination of components through which light is transmitted in the imaging lens 10, and may include one or more of a lens barrel 120, a lens, and a spacer ring 140. The light-transmitting component 100 defines a light path axis 101, and external light passes through the light-transmitting component 100 along an extending direction of the light path axis 101, where the light path axis 101 is a theoretical central axis of each component in the light-transmitting component 100, and a position of the light-transmitting component 100 varies with a shape and a position of the light-transmitting component 100.
The light-transmitting component 100 includes an accommodating groove 110 extending around the optical path axis 101, the accommodating groove 110 is formed on one part of the light-transmitting component 100 extending around the optical path axis 101, and the shape of the accommodating groove 110 may be a ring shape, a polygon shape, or other regular patterns or even irregular patterns, which is not limited herein.
