A lens barrel includes a lens barrel surrounding wall and a cover member. The lens barrel surrounding wall surrounds an optical axis. The lens barrel surrounding wall includes a lens element accommodating portion abutted against lens elements. The lens barrel surrounding wall has an object side connecting surface closest to an object side and facing the object side. An inner diameter of the lens element accommodating portion closest to the object side is greater than an inner diameter of the lens element accommodating portion closest to an image side. The cover member has an image side connecting surface facing the image side. The image side connecting surface of the cover member is fixed on the object side connecting surface of the lens barrel surrounding wall, wherein a maximum outer diameter of the cover member is less than or equal to a maximum outer diameter of the lens barrel surrounding wall.

Lens barrel

An optical imaging lens, sequentially including at least one lens element and an optical ring element from an object side to an image side along an optical axis, is provided. The optical ring element is located on a side of the lens element closest to the image side and facing the image side, and has an object-side bearing surface facing the object side and in contact with the closest lens element. The object-side bearing surface has an object-side outer periphery and an object-side inner periphery, and the object-side inner periphery is located between the optical axis and the object-side outer periphery. The object-side bearing surface has at least one groove, and the at least one groove extends to the object-side inner periphery along a radial direction.

Optical imaging lens

An optical lens assembly including at least two lens elements and an adhesive is provided. The lens elements are stacked disposed, and each of the lens elements includes an optical portion allowing imaging rays to pass through and an assembly portion configured to fix the lens. Each of the assembly portions of two adjacent lens elements includes an adhesive surface, and the adhesive surfaces are disposed opposite to each other to form an adhesive gap. The adhesive is distributed in the adhesive gap and adhered to fix the adhesive surfaces disposed opposite to each other. The adhesive surface of one lens element extends outwardly towards a direction away from an optical axis of the lens element to form an adhesive entering tapered surface configured to guide the adhesive into the adhesive gap.
