Abstract:
A method for manufacturing an ink jet recording head having an orifice for liquid discharge, a nozzle communicating with the orifice, an electrothermal converting member arranged on a substrate in the nozzle to form a bubble in the liquid by generating thermal energy, and a liquid chamber communicating with the nozzle to supply the liquid to the nozzle, said method comprising the steps of:preparing the substrate to be a silicon substrate having (100) plane or (110) plane crystal axes;forming an organic resin layer at least in a liquid chamber portion of the substrate, on an electrothermal converting member side of the substrate; andforming an elastic member portion of the organic resin layer in the liquid chamber portion of the substrate by removing by means of anisotropic etching a part of the the liquid chamber portion of the substrate from a side of the substrate opposite to the organic resin layer.
