Abstract

PURPOSE:To protect the resistor from deterioration and provide excellent printing characteristics by providing each insulator with a taper, in the thermal head comprising a resistor provided on each insulator projecting on a substrate. CONSTITUTION:After a layer of the insulator is formed on the entire upper surface of the insulated substrate 1 and a photoresist is printed on those portions of the insulator which are intended to constitute stripes 7 after the subsequent photoetching, the unrequired portions are removed by ion etching 9. When conducting the ion etching, the ion beam is not allowed to be irradiated perpendicularly to the insulated substrate 1 but is caused to be irradiated at an angle theta to the substrate 1, while the substrate 1 is rotated in a horizontal plane, whereby the stripe 7 is provided with a taper according to the inclination of the ion beam.
