ABSTRACT:
A method of manufacturing an ink jet head including 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 5C; bonding an elastic plate on the portion 5C; and integrating the bonded plates while hardening them by heating.
