METHOD OF MANUFACTURING INK JET HEAD

摘要

A method of manufacturing an ink jet head comprising the steps of: laminating a dry film photoresist (51) on an inner surface of a nozzle plate (2), the dry film photoresist being a photohardening resin; exposing the photoresist (51) with such energy as to half-harden the photoresist while superposing thereon a photomask (M1) having a predetermined masking pattern; developing the thus exposed photoresist (51); laminating a photoresist (52); secondarily exposing the photoresists (51), (52) to form a partially hardened portion (51C); bonding an elastic plate on the portion (51C); and integrating the bonded plates while hardening them by heating.
