摘要：
A thermal head includes a support substrate having a concave portion formed in its front surface, and an upper substrate bonded in a stacked state to the front surface of the support substrate. A heating resistor is provided on the front surface of the upper substrate at a position corresponding to the concave portion. A pair of electrodes are provided on opposite sides of the heating resistor, and a convex portion is formed in the front surface of the upper substrate between the pair of electrodes. The heating resistor has a heating portion disposed between and not overlapped by the electrodes, and the heating portion directly overlies the concave portion. The convex portion has a width dimension smaller than that of the heating portion.
