ABSTRACT:
A method of producing an ink-jet type printer head wherein a plurality of plate-shaped piezoelectric members are stuck onto the surface of a low-rigidity member so that they are disposed adjacent to the low-rigidity member. A plurality of grooves extending from the surfaces of the piezoelectric members to the inside of the low-rigidity member are defined by grinding in parallel at given intervals inclusive of positions at which the grooves extend through joints between the adjacent piezoelectric members. In addition, posts are formed on both sides of each of the grooves and electrodes are disposed on both inner sides of each groove. A roof is stuck on the surfaces of the piezoelectric members so as to define a plurality of pressure chambers having one end in which a plurality of nozzles are formed.
