Abstract
The present invention provides an ink jet print head that enables an optimum resistance value to be set for a heating resistor that generates ink ejection energy to allow high-quality images to be printed, as well as a method for manufacturing the ink jet print head. Heating resistors with sheet resistance values differing from each other are formed on the same substrate by heating resistant layers.
