Document Type and Number:
Japanese Patent JP4949860
Kind Code:
B2
Abstract:
A method for producing an optical lens unit, the optical lens unit including a lens and a metallic lens barrel that holds the lens therein, includes forming the lens barrel so as to be a hollow cylinder and so as to have an inclined surface, formed on the inner wall of the lens barrel, extending from a position adjacent to a first opening to a position adjacent to a second opening and being tilted at a tilting angle ranging from 10° to 20°; and placing a spherical lens base on the inclined surface formed on the inner wall of the lens barrel, heating the lens base in this state such that the lens base is bonded to the inner wall of the lens barrel by pressure, heating the lens base again, and shaping lens surfaces adjacent to the openings of the lens barrel.
