PROBLEM TO BE SOLVED: To provide an image pickup lens unit manufacturing method capable of forming a holder member with a small number of components, and avoiding generation of a ghost or flare due to a positioning shape, an appearance problem, deterioration of dimensional accuracy, damage of a lens when being set, and other problems.SOLUTION: In an installing step of the image pickup lens unit manufacturing method, since a lens 10 is positioned by one pressing member (protrusion) 61d of protrusions 61d and 62d which are a pair of pressing members disposed in a position corresponding to a pair of openings OP1 and OP2 by molds 51 and 52, it is possible to reliably fix the lens 10 in the molds 51 and 52 in a state of not affecting a shape of a holder member 40 without interrupting the molding of the holder member 40. Thus, it is possible to avoid deterioration of the dimensional accuracy resulting from a large positioning shape remaining on the holder member 40. In addition, since the holder member 40 is molded in a batch, it is possible to avoid an increase of the number of components used for the assembling the holder or complication of component shapes at a connecting portion.SELECTED DRAWING: Figure 7 |
