Zusammenfassung:	PURPOSE:To provide a printing head less liable to be abraded or consumed, by coating an exposed tip part of a conductor pattern with a head metal or a head alloy, in a printing head. CONSTITUTION:An exposed etched surface of the conductor pattern 2 is overcoated with an insulating resin, and a tip part of the printing head is cut at a predetermined part (line A-A) to expose electrodes. Then, a terminal part on the opposite side of the head tip part is connected to a power source, and the tip part is immersed in, for example, a chromium plating bath, and an electric current is passed with a current density of 50A/cm for 5min, whereby chromium is deposited as tip parts 5 in a thickness of 3-5mum. In the case of such plating, Co, Ni, Ni-P or the like can be used as the hard metal or alloy.
