Patent ID: 7976134

Claim:
A method of manufacturing a liquid ejecting head including a flow channel unit having pressure generating chambers in a parallel arrangement, a piezoelectric element unit having a plurality of piezoelectric elements and a fixed substrate, and a case head having a storage portion and a first magnet, the method comprising: inserting positioning pins into positioning holes in the head case and the flow channel unit, wherein the positioning holes in the flow channel unit are formed on opposite ends and in the direction of the parallel arrangement of the pressure generating chambers; joining the case head and the flow channel unit; inserting the piezoelectric element unit into the storage portion of the case head while causing the fixed substrate to abut an alignment surface of the storage portion of the case head by a magnetic field of the first magnet; and joining the fixed substrate of the piezoelectric element unit, the case head, and the flow channel unit; wherein the alignment surface is an inner surface of the storage portion of the case head; wherein the first magnet is disposed on an exterior surface of the case head opposite the alignment surface of the storage portion of the case head; and wherein the fixed substrate is formed of a magnetic material.
