<p>PURPOSE:To form a thermal head reduced in driving force, by providing a resistor and an electrode conductor on the glaze layer provided on an insulating substrate and forming one of the resistor and the glaze layer out of a porous body. CONSTITUTION:A glass paste forming porous glass is applied to the upper surface of an insulating substrate 1 and baked to form a glaze layer 2a. Subsequently, a resistance paste having a proper amount of trichlene mixed therein is printed on the glaze layer 2 and baked to form a resistor 4a to constitute a thermal head. Because this thermal head is increased in the heat insulating property of the glaze layer 2a thereof, the heat capacity of the printed part thereof, that is, the part containing the resistor 4a, a protective layer 5 and electrode conductors 3a, 3b becomes low and, further, the same effect as the increase in heat resistance is developed and the reduction in driving power can be realized.</p> |
