PROBLEM TO BE SOLVED: To obtain a process for manufacturing a thermal head through a simple process while decreasing the common resistance. SOLUTION: At first, a thin Al conductor film 5 is formed on a resistor film 4. The Al conductor film 5 on an area of the resistor film 4 becoming a heating resistor 4a is then removed and a common electrode 5a and a discrete electrode 5b conducting, respectively, to the opposite sides of the heating resistor area are formed. Subsequently, a first plating seed layer 6a is formed on the thick film electrode forming area of the common electrode 5a by lift-off method and a common thick film electrode 7 for decreasing the resistance of the common electrode 5a is formed on the first plating seed layer 6a by plating.
