ABSTRACT:
An object of this invention is to provide a manufacturing method that, by using a general-purpose semiconductor fabrication process, can easily manufacture an ink jet print head in which energy generating elements are complicatedly installed in the ink path. To this end, the present invention comprising steps of providing a substrate having a removal projected portion, forming an energy generating element along the projected portion, forming a supporting member on the energy generating element, and forming a ink chamber by removing the projected portion from the substrate.
