A thermal printhead includes a substrate, an electrode layer formed on the substrate, and a heating resistor which is formed on the electrode layer and contains a conductive substance and glass. The conductive substance of the heating resistor is doped in advance with an insulating substance which is identical in crystalline structure to the conductive substance. The heating resistor is formed by mixing powder of the insulating substance, which is identical in crystalline structure to the conductive substance, with the conductive substance powder, baking the obtained mixture, pulverizing the baked mixture, mixing the pulverized mixture with glass powder to prepare a resistor paste, and printing and baking the obtained resistor paste.
