IMAGE CAPTURING LENS UNIT PRODUCTION METHOD, AND IMAGE CAPTURING LENS UNIT

摘要

Disclosed is an image capturing lens unit which is advantageous when produced in a small size, wherein the number of components are not increased, a holder main body and a cover can be easily connected without providing a resin flow path for connection, and the occurrence of ghosts, flares, or the like caused by a positioning shape can be prevented. A lens (10) is inserted in a first holder member (20) and positioned while the first holder member (20) remains in a die. In the second molding step, a second holder member (30) is formed to prevent separation of the lens (10), so that the lens (10) is welded to the first holder member where the lens is positioned. Therefore, molding of the second holder member (30) and attachment to the first holder member (20) can be reliably performed at the same time, and thus, the number of components required for assembling holders can be prevented from increasing. Further, providing a resin flow path is not necessary for connecting the first holder member (20) and the second holder member (30), and thus, the image capturing lens unit can be downsized. In addition, deterioration in size accuracy caused by a large positioning shape remaining on the first holder member (20), etc., can be prevented.
