Abstract
The electrostatic ink-jet recording head has a head member having a chamber for supplying and discharging ink, a head chip in which a plurality of continuous meniscus shapes are respectively formed on groove portions, a cover plate formed so as to expose a part of the corners of the groove and flange portions, and a protruded member on which pectinate protrusions are formed at the same intervals as those of the meniscus shapes formed on the head chip. A recording electrode is formed on each groove portion. Each protrusion of the protruded member is set on each groove portion of the head chip and moreover, formed so as to be protruded beyond the corner of the flange portion.
