Title:
圧電体装置及びその製造方法
Document Type and Number:
Japanese Patent JP4357659
Kind Code:
B2
Abstract:
A piezoelectric device having improved characteristics is accomplished by restricting degradation and variance of vibration characteristics resulting from an adhesive, and a production process is simplified. The piezoelectric device has a construction in which a ultra-fine particle layer made of substantially the same main component and having the same crystal structure as those of a piezoelectric layer is formed on a substrate, and the piezoelectric layer is formed on the ultra-fine particle layer.
