Abstract
PURPOSE: To obtain a metal slit plate with high preciseness due to both surface etching processing by carrying out etching processing by using two kinds of work masks with a different pattern for forming a precise surface and a reinforced surface.
CONSTITUTION: By a known process, a work mask 5a to which a pattern such as a slit or the like is formed for forming a precise surface of a metal plate and a work mask 5 to which a pattern for forming a reinforced surface of which a diameter of a central pore is larger than that of the mask 5a are formed. Next, the masks 5, 5a with a different pattern are respectively attached to acid resistant photosensitive agents 6, 6. Subsequently, both surfaces of thus formed base plate is exposed and developed by a triclene vapor and the resultant base plate is subjected to etching treatment by a specifically compounded etching liquid containing a surfactant to etch Ni layers 2, 2a. During this time, a copper layer 3 is not almost etched. Then, the photosensitive agents 6, 6 are peeled, the copper layer 3 is etched by an alkaline etching liquid to fabricate the metal slit plate provided with plural slit pores and a central pore 8.
