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.
