ABSTRACT:
A thermal recording head comprising an insulating substrate which has thereon a heat generating resistor pattern made of a thin-film resistor, an electrode pattern having a common power supply electrode pattern portion and a common grounded electrode pattern portion, for supplying the power to the resistor pattern, and a controlling electrode pattern portion, and switching elements for controlling the supply of the power to the resistor pattern. The electrode pattern is made of a thick-film copper paste by a printing process. The operation of the switching elements is controlled by the controlling electrode pattern portion.
Also disclosed is a process for manufacturing a wiring substrate for a thermal recording head.
