Inkjet head and manufacturing method of the same

摘要

A surface electrode is provided on a surface of a piezoelectric element for changing the volume of each pressure chamber in an inkjet head. The surface electrode has a main electrode portion opposed to the pressure chamber and a connecting portion not opposed to the pressure chamber. A land is provided on one end of the connecting portion of the surface electrode. The land is electrically connected to the surface electrode. When the land is connected to a terminal of an FPC, a driving signal can be transmitted to the surface electrode. The land is therefore connected to the terminal using solder and a thermosetting resin covering the surface of the solder, or using only a thermosetting resin.
