摘要： A stable operation is realized without any malfunction of a driver even under a voltage condition that a supplied voltage is 3.3 V or lower. For this purpose, in an ink-jet printhead having an ink orifice for discharging ink, a plurality of heat generation elements for generating heat energy used to discharge ink, and an ink channel which incorporates the heat generation elements and communicates with the ink orifice, a driver for driving the heat generation elements, and a logic circuit for controlling the driver are formed on a single board. The gate oxide film thickness of an enhancement NMOS transistor which forms the driver is larger than that of an enhancement NMOS transistor which forms the logic circuit.
