Abstract

PURPOSE: To obtain the title matrix which enhances the sharpness and touch of an electric razor, increases the strength of the outer edge, and enables the inner edge to be stabilized, by forming an insulating film of photosensitive resin or the like on the perforated portion of the outer edge and recessing the back side of an electrically conductive matrix substrate, followed by plastic working such as drawing.
CONSTITUTION: Insulating substance (film) 4 such as photosensitive resin is formed on electrically conductive matrix substrate 2, and part of a portion corresponding to netted edge portion 3 of a domed matrix, e.g. the back side of shadowed portion 1 is recessed by etching or mechanical working. When the substrate is drawn with a punch, etc., because of the insufficient thickness of the recess, the substrate escapes to the punch side, forming a recess on the surface of the matrix. By arranging long hole portion 5 on the boundary of the projection in the nedtted edge pattern for the outer edge, vicious hair and a long mustache is more efficiently introduced
