INK JET RECORDING APPARATUS

摘要

PROBLEM TO BE SOLVED: To lower costs by reducing the number of components. SOLUTION: Perpendicular walls 5 extending to side faces of a base 4 are formed to at least two opposite sides of a peripheral edge of a flat part of a nozzle plate 1 where nozzle openings 8 are formed. The perpendicular walls 5 are made fixing means for a channel substrate-protecting material and the base 4.
