A thermal head which can effectively use a thin film ribbon as an ink ribbon, and take a relatively long edge distance. The thermal head has its object to maintain transferring property of the ink to a recording medium and to maintain high printing quality for a long period of time. A heating portion is formed from the top of a heat insulating layer to a slope of the common electrode side of the heat insulating layer, and a gap is formed on the common electrode. The ink ribbon is pressed into contact with the recording medium at a portion of low-temperature of the top of portion of the heat insulating layer falling outside the center portion of the heating portion where a pressure of the printer to the platen is mainly applied.
A thermal head comprising:
A thermal head for a thermal transfer printer, the thermal transfer printer including a platen and means for moving the thermal head in a printing direction relative to the platen, the thermal head comprising:
