Abstract
A thermal printer has a support substrate with a concave portion in a surface thereof, and an upper substrate bonded to the surface of the support substrate and including a convex portion at a position corresponding to the concave portion. A heating resistor is provided on a 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, with each of the electrodes being formed in a region outside of the convex portion. The convex portion extends at a height greater than each of the electrodes. At least one of the pair of electrodes has a thin portion connected to the heating resistor in a region corresponding to the concave portion, and a thick portion connected to the heating resistor and having a thickness greater than that of the thin portion.
