    • A piezoelectric thin film resonator that ensures the strength of a membrane without degrading the resonant properties and which can be easily handled in mounting. The piezoelectric thin film resonator has a substrate, a thin film member, and reinforcing films. The thin film member has at least two support portions supported by the substrate and a floating portion disposed over the substrate with a space provided therebetween and supported by the support portions. The floating portion includes a pair of excitation electrodes facing each other and a piezoelectric thin film provided therebetween. The reinforcing films are formed in the vicinities of the boundaries between the floating portion and the support portions of the thin film member.
    • 一种压电薄膜谐振器,其确保膜的强度而不降低谐振特性,并且可以在安装时容易地处理。 压电薄膜谐振器具有基板,薄膜构件和增强膜。 薄膜构件具有由基板支撑的至少两个支撑部分和设置在基板上方的浮动部分,其间设置有由该支撑部分支撑的空间。 浮动部包括彼此面对的一对激励电极和设置在它们之间的压电薄膜。 增强膜形成在浮动部分和薄膜构件的支撑部分之间的边界附近。
