ABSTRACT:
An ink jet type recording head is capable of preventing the occurrence of cracks in a portion close to the circumferential wall of the pressure generating chamber of the piezoelectric active section so as to enhance the durability of the recording head.
The ink jet type recording head includes a piezoelectric vibrator having a vibrating plate composing a portion of a pressure generating chamber communicated with a nozzle opening, the upper surface of the vibrating plate functioning as a lower electrode, the piezoelectric vibrator also having a piezoelectric active section composed of a piezoelectric layer formed on the surface of the vibrating plate and also composed of an upper electrode formed on the surface of the piezoelectric layer, the piezoelectric active section being formed in a region opposed to the pressure generating chamber, wherein the vibration regulating section is composed of a wide width section in which the piezoelectric layer is wider than the primary portion of the piezoelectric active section, and the wide width section is extended to a side wall and arranged on one end side of the pressure generating chamber in the longitudinal direction.
