Abstract
A method for producing a metal filter comprises a lamination step, an exposure step, a development step, a plating step, a dissolution step, and a stripping step. The method is useful because it is possible to produce a metal filter in which there are not damages such as wrinkles, folds, scars, and curls and deformation of fine through-holes.
