The present invention corrects variations in characteristics of each printing element of a printing head to print high-grade images. To achieve this, the present invention provides an ink jet printing head that uses thermal energy generated by a heat-generating resistor to eject an ink from an ink ejection opening, wherein a plurality of wirings with different wiring resistances are connected to the heat-generating resistor. A transistor selected one of the plurality of wirings to conduct current through the heat-generating resistor.
