Abstract
A liquid ejection head and its manufacturing method are capable of reducing the thickness of a protective layer as compared to the traditional technique so as to efficiently transfer the heat energy generated by a heating resistance element to a droplet of liquid such as ink. To achieve this, power supply wirings are provided in the same layer below the heating resistance element.
