ABSTRACT:
A recording head for discharging ink by using thermal energy comprises a plurality of outlets for discharging ink and a substrate including a common substrate plate of P type, a plurality of electrothermal converting elements and a plurality of functional elements connected to the respective electrothermal converting elements and formed on the common substrate plate as well as the electrothermal converting elements. Each of the functional elements has a first semiconductor region of N type, a second semiconductor region of P type provided within the first semiconductor region and a third semiconductor region of N type provided within the second semiconductor region, so as to form a rectifying junction. The first, second and third semiconductor regions are formed by diffusion of impurity atoms in the common semiconductor substrate plate.
