Abstract
PURPOSE: To remove a short part without breaking the essential part by a method wherein a pattern of an electrode layer and a resistor layer is formed on a support, then a resist pattern wider than said pattern is formed thereon and etching is conducted.
CONSTITUTION: A wiring pattern 2 consisting of the electrode layer and a resistor layer is selectively formed on top of the support 1, and the pattern of the resist layer 3 wider than the wiring pattern 2 is formed on the wiring pattern 2. Thereafter, a defective part, e.g., the short part 4 formed on the support 1 is removed by etching without damaging the essential part, i.e., the wiring pattern 2. Thus, a thermal head free of defects is obtained.
