摘要： A printing head is intended to achieve high reliability and a production method of the printing head is intended to achieve high yield at low cost. A liquid ejecting printing head employs a base body, in which an electrothermal transducer element, a driving functional element for driving the electrothermal transducer element, a wiring electrode connecting between the electrothermal transducer element and the driving functional element, and an insulation layer provided on the wiring electrode are formed on a substrate. The electrothermal transducer element has a heat generating resistor formed of a material selected from the group consisting TaN, HfB2, Poly-Si, Ta—Al, Ta—Ir, Au and Ag. A protective layer above the heat generating body is formed of an insulative compound deposited to be low density to high density in order. The protective layer is formed by depositing the insulative material in the electrothermal transducer element or the wiring electrode with elevating the temperature of the base body from low temperature to high temperature.
