An inkjet print head wherein the surface (front surface) for ejecting ink droplets coming from an ink channel partitioned by a drive wall composed of a piezoelectric device is arranged opposite to the surface (back surface) for supplying ink coming to the ink channel. The connection electrode for driving the piezoelectric device is pulled out to the back surface, and the back surface is a photosensitive glass substrate wherein the ink feed apertures manufactured by exposure and etching process, and the drive wires electrically connected with the connection electrode are formed.
