摘要：
This invention has as its object to provide a substrate for an ink jet recording head, which is compact and can realize stable recording with high reliability, a recording head using the substrate, a recording apparatus mounting the recording head, and a method of driving the recording head.There are disclosed a substrate for a thermal recording head, having a plurality of heating resistor elements, a plurality of wiring electrodes for supplying driving signals to the heating resistor elements, a function element, electrically connected to the heating resistor elements, for selectively driving the plurality of heating resistor elements, and a measurement resistor element which is electrically independent from the heating resistor elements and the function element, and has a resistance value larger than that of each heating resistor element, an ink jet head, a head cartridge, and a recording apparatus utilizing the substrate, and a method of driving a recording head using a measurement resistor.
