ABSTRACT:
A thermal head for printers, facsimile machines, copying machines, etc., of the thermo-sensitive type or thermo-transfer type, includes a substrate and a resistance-heating element on the substrate. The substrate has a printing surface relative to which an information carrier is caused to slide for printing information on the information carrier. The substrate comprises a material having a thermal conductivity coefficient and a heat capacity per unit volume which are within respectively defined numerical ranges. The resistance-heating element is formed on a thin-walled portion of the substrate, and the printing surface is made integral with a substrate surface which is adjacent to the resistance-heating element.
