<P>PROBLEM TO BE SOLVED: To provide an ink jet print head capable of reducing a driving voltage of the ink jet print head by including a projecting part for reducing the space of a pressure chamber and manufactured through a simpler process by forming the projecting part on an upper silicon layer of a lower substrate formed of an SOI wafer, and a method for manufacturing the ink jet print head. <P>SOLUTION: There are provided an ink jet print head and a method for manufacturing the ink jet print head. The ink jet print head includes: an upper substrate including a pressure chamber formed therein; and a lower substrate including an upper silicon layer, an insulating layer, and a lower silicon layer. The lower substrate includes a projecting part formed of the upper silicon layer and projected into an inside of the pressure chamber in order to reduce the space of the pressure chamber, and a bottom face of the upper substrate and an upper surface of the lower silicon layer of the lower substrate can be fixed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
