摘要： A lens holder for alignment of a stacked lens module and a manufacturing method thereof are revealed. A stacked lens submodule disposed with at least one first alignment fixture is used as a molding insert to be set into a mold arranged with a second alignment fixture where the first alignment fixture connects with the second alignment fixture correspondingly. Then by injection or press molding of the embedded molding insert, a lens module with the lens holder for alignment is formed. Thereby the conventional manufacturing method of the lens molder is improved, the processes are simplified and the yield rate is increased. Moreover, the molded lens module is packed into the lens more easily so that it is suitable to be applied to camera lenses, small lenses and mobile phone lenses.
