Abstract
A thermal head avoids a drop in print quality caused by adhesion of printing chaff. A thermal headthat presses against thermal paper that moves from one side to the other side and prints by melting dye contained in the thermal paper has a glazed layerthat is formed in an area on one part of a ceramic substrateand stores in-flowing heat, and a heating resistorthat is located offset to one side from the center of the glazed layer, selectively heats the thermal paper S pressed in contact therewith, and melts a dye material contained in the thermal paper. A smooth surface P against which the thermal paper S heated by the heating resistorslides is formed to the other side of the glazed layerfrom the heating resistor
