<p>PURPOSE:To reduce the dispersion of resistance value of a heating resistor by forming an electrode pattern on the upper surface of a heat resistance layer 2 and providing a heating resistor using a photoregist. CONSTITUTION:A photoregist 5 is applied in such a manner as to cover a heat resistance layer 2 and an electrode pattern 3. After drying the photoregist 5, it is exposed to light so that the photoregist 5 may be removed only an an area where a heating resistor is printed. After the exposure, it is developed and dried and a groove 6 is formed on the area where the heating resistor is printed. When the groove 6 has been formed, the heating resistor is printed even in the groove 6 to such a depth that the former almost goes beyond the edge of the groove. After this process, the area is dried and backed in the mean time, the photoregist 5 is completely removed, thus forming a heating resistor easily. In this way, a heatsensitive recording head of thick film type having a minimum dispersion of the form of a heating resistor is manufactured.</p> |
