摘要 |
The present invention provides a thin piezoelectric film having a high piezoelectric strain constant and a good adhesion with a lower electrode which can be produced without being cracked. The present invention also provides an ink jet recording head comprising this thin piezoelectric film as a vibrator. The thin piezoelectric film element of the present invention comprises a PZT film 14 made of a polycrystalline substance, and an upper electrode 16 and a lower electrode 12 arranged with the PZT film interposed therebetween. The grain boundary of the crystalline constituting the PZT film is present almost perpendicular to the surface of the electrode. Further, the orientation of the crystalline constituting the PZT film is controlled to a desired range. <IMAGE> |
