Abstract
A record head for an electrostatic ink jet recorder includes a head chip implemented as a laminate of alternating flat conductors and flat insulators and etched by an etching liquid reactive only to the material of the insulators. The conductors readily turn out ridges protruding from the head chip and having a high aspect ratio. The ridges each serve as an ejection electrode.
