Abstract

PURPOSE: To permit the formation of an accurate and uniform fine slit interval by the procedure in which a filter wire and a spacer wire are closely wound around a particularly shaped metallic core together, the ends of wires are fixed, and then the spacer wire is removed by dissolution.
CONSTITUTION: The filter wire 4 and the spacer wire 5 are closely wound around a particulary shaped metallic core 1 together and then the ends of the wires are fixed so as to keep the slit interval (d) constant. In this case, the weld 6 is formed between the core 1 and the filter wire 4 for reinforcement, or the interval-holding wire 7 is provided in a right-angled manner on the outside of a filter wire 4 having an interposing spacer wire 5 and then the weld 8 is preferably formed at the intersections between both wires 4 and 7. Then, the whole is dipped in an acid, etc., to dissolve and remove the spacer wire 5 alone in order to obtain the filter 9. Thus, the slit interval (d) can be formed uniformly at 40 microns or less.
