PROBLEM TO BE SOLVED: To provide a simple mold manufacturing method for a microlens array and to provide a high-performance reading device by creating a lens array with the mold and mounting the lens array. I do. SOLUTION: A required number of times are repeatedly pressed on a surface of a substrate mirror-finished with a single punch having a curved surface shape required for forming a microlens at a tip thereof while forming a desired pitch as a lens array. Then, a member to be a mold is created. Next, using this mold, micro aspheric lens arrays 11 and 12 are formed on a transparent parallel flat plate (micro lens array glass substrate) 10 using an ultraviolet curing resin. Create |
