Abstract
A thermal head has a support substrate including a concave portion formed in a front surface thereof. An upper substrate is bonded in a stacked state to the front surface of the support substrate and includes a convex portion formed within a region corresponding to the concave portion. A heating resistor is provided on a front surface of the upper substrate at a position straddling the convex portion. A pair of electrodes is provided on both sides of the heating resistor. At least one of the pair of electrodes has a thin portion and a thick portion. The thin portion is connected to the heating resistor at one of a side surface and a top surface of the convex portion in the region corresponding to the concave portion. The thick portion is connected to the heating resistor and is formed thicker than the thin portion.
