Title: Method of manufacturing thermal head

Abstract: A method for manufacturing a thermal head comprises forming a heat generating resistor on an insulative substrate, and disposing conductors having different material properties on the heat generating resistor for supplying power to the heat generating resistor. The conductors are then etched to form a wiring electrode having a tapered peripheral edge portion as a result of the different material properties of the conductors. A protective film is then formed over the heat generating resistor and the wiring electrode.
