摘要：
A thermal head has a heat storage layer bonded onto a surface of the substrate, a heating resistor provided on the heat storage layer, and a pair of electrode portions connected to the heating resistor. The heating resistor has a heating portion which does not overlap the pair of electrode portions. A hollow portion is provided in a region of at least one of the surface of the substrate and a surface of the heat storage layer, the region being opposed to the heating resistor. A center line of the hollow portion is shifted with respect to a center line of a heating portion of the heating resistor.
