  • Patent number: 8982486
    Abstract: An image pickup lens unit, in which a holder body and a cover can be easily connected together, without additional components and a resin flow path for the connection. A lens 10 is positioned in a first holder member 20 which remains in a mold. A second holder member 30 for preventing the lens 10 from falling off is molded such that it is welded to the first holder member having the lens 10 positioned therein. This facilitates molding of the second holder member 30 and joining of the second holder member 30 to the first holder member 20 at the same time. Since there is no need to provide a resin flow path for joining the first holder member 20 and the second holder member 30 together, the image pickup lens unit can be made small in size.
