ABSTRACT:
A method of forming a plate having a plurality of uniform and precisely sized fine bores. The method comprises winding around a mold member a wire having a diameter equal to that of the fine bores to be formed, forming an electro-cast layer on the mold member, superposing and uniting another mold member to the first-mentioned mold member, removing only the wire to a predetermined depth to form a mold, forming a plurality of plastic sheets using this mold, effecting a treatment for obtaining a conductivity on each plastic sheet to form an electro-cast master, forming an electro-cast film using this electro-cast master and separating the electro-cast layer thereby to form the plates having fine bores dispersed and sized uniformly and finished at high circularity and cylindricalness.
