Abstract

PURPOSE:To improve printing performance by improving thermal contact between a heat-genarating section and a coloring paper, by providing an electrically insulated layer on the top layer of a heat-generating resistor of a thermal head, and then, by covering the layer partially with a metal of good thermal conductivity and high hardness. CONSTITUTION:On a thermally conductive substrate 1 such as alumina ceramics, etc., a glaze layer 2, a resistor layer 3 and an electrode 4 to be connected to the latter layer are provided, and on the top layer, an electrically insulated layer 6, such as SiO2, etc., which is also capable of serving the purpose of an oxidation preventing film of the heat-generating resistor, is provided. Further, a metal dot 7 of high thermal conductivity, such as Ni, etc., is provided as a friction preventing layer only in a concave section which is to become a heat-generating section.
