摘要： A piezoelectric element includes two electrode films and a layered piezoelectric film which is sandwiched between the electrode films and made of two thin piezoelectric films each having preferred orientation along the (111) plane. The two thin piezoelectric films are aggregates of columnar grains, respectively, which are continuously linked to each other. The columnar grains of the second thin piezoelectric film have a larger average cross-sectional diameter than the columnar grains of the first thin piezoelectric film. The ratio of the thickness of the layered piezoelectric film to the average cross-sectional diameter of the columnar grains of the second thin piezoelectric film is 20 to 60 inclusive.

摘要： An apparatus of forming thin films, which is small and requires a short thin-film formation time, is provided which comprises at least one physical vapor deposition device and at least one chemical vapor deposition device, wherein said physical vapor deposition device and said chemical vapor deposition device are provided with an exhaust pipe respectively for connection with a common exhaust means and an exhaust switching means. A method of forming thin films using this apparatus is also provided. According to the configuration in which the exhaust switching means is connected via exhaust pipes to the physical vapor deposition device, to the chemical vapor deposition device, and to the exhaust means, this apparatus can be accomplished in a small size which has at least two chambers and one exhaust means. In this way, thin films can be formed in a short thin-film formation time with a small apparatus, since vapor of a starting material which is led in at the time of chemical vapor deposition does not enter the physical vapor deposition device.

A resistor is formed on part of the upper surface of the oxygen conductive thin film located in the through hole. Thus, the oxygen ion conductive thin film can be directly heated by the resistor, so that oxygen ions can be speedily transferred with a low power. Therefore, the oxygen ion conductivity of the oxygen ion conductive thin film can be improved.
