ABSTRACT:
A method for manufacturing an ink jet printing head comprises a step of joining together a base board having ink discharge pressure generating elements, which also forms the bottom of a plurality of ink paths, and a ceiling plate that forms the ceiling portion of the plurality of ink paths in order to provide an ink jet printing head. In this method, either one of the joining portions between the base board and ceiling plate is Si and the other one of them is metal, and after each of the joining portions is irradiated by an energy particle, the base board and the ceiling plate are made in contact and cold joined by the application of cold activation. With the method of manufacture thus provided, it is possible to make the intensity of joint between the ceiling plate and base board firmer so as to eliminate any gaps between them, hence preventing the creation of cross talk phenomenon, and the degradation of quality of printed images as well.
