ABSTRACT:
The method manufactures a liquid ejection head having a diaphragm which forms a portion of pressure chambers connected to nozzles ejecting liquid, and piezoelectric elements which deform the diaphragm. The method includes the steps of: applying a photosensitive resin on at least a portion of each of electrodes of the piezoelectric elements; bonding a substrate having through holes, to the photosensitive resin; exposing the photosensitive resin via the through holes; developing the exposed photosensitive resin, thereby forming holes connecting to the through holes in the photosensitive resin; and filling conductive material into the through holes and the holes formed in the photosensitive resin.
