Abstract
Official abstract text for this publication.
Provided are a vibrating body and a vibration wave actuator, which can suppress vibration attenuation along with a reduction in size with an inexpensive structure, to thereby improve vibration efficiency, and can output stable vibration energy. A vibrating body includes: a piezoelectric element including a piezoelectric layer and an electrode layer; a ceramic substrate to which the piezoelectric element is fixed; and a ceramic layer including the same main component as a main component of the ceramic substrate, which is provided between the piezoelectric element and the ceramic substrate, and the piezoelectric element is fixed to the ceramic substrate through intermediation of the ceramic layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A vibrating body, comprising: a piezoelectric element comprising a first piezoelectric layer and an electrode layer; a ceramic substrate; and a ceramic layer comprising as a main component the same main component of the ceramic substrate, wherein the piezoelectric element is fixed to the ceramic substrate with the ceramic layer interposed between the piezoelectric element and the ceramic substrate, wherein the ceramic layer comprises glass, wherein…
