PURPOSE: A lens assembly and a manufacturing method thereof are provided to reduce material costs and to simplify process, thereby improving production efficiency. CONSTITUTION: A lens assembly(100) is composed of a body tube(110), a second lens(121), a first lens(125), an inducing groove(126), a spacer(130), and a bonding groove(131). A receiving part is formed in the inner side of the body tube. The first lens is inserted in the receiving part and forms the inducing groove on the outer circumference. The spacer forms the bonding groove which is communicated with the inducing groove and is inserted into the receiving part. The spacer is included in one side of the first lens. The second lens is inserted into the receiving part. Adhesive is filled in the bonding groove through the inducing groove and combines the body tube with the first lens. |
