Abstract
PURPOSE: To obtain a thermal head with a pattern of high precision by a method wherein after a resistor layer and a conductor layer are uniformly laminated on a substrate, or after the thus obtained laminate is etched to form a desired pattern, the laminate is subjected to a light etching treatment.
CONSTITUTION: The resistor layer and the conductor layer are uniformly laminated on the substrate, and the desired pattern is formed by etching the laminate to produce the thermal head. In this case, after laminating the conductor layer or after forming the pattern, the laminate is subjected to the light etching treatment to roughen the surface of the conductor layer. The light etching treatment consists in lightly etching a surface layer of about 0.1W0.3μm in thickness, and it may be conducted following to forming the conductor layer or may be conducted after forming the pattern for the thermal head.
