Abstract:
本发明提供一种层叠体及其制造方法。层叠体（1）具备陶瓷基板（11）、压电元件（10）、和中间层（15）。压电元件（10）具有下部电极（12）。中间层（15）形成于基板（11）和压电元件（10）的下部电极（12）之间。中间层（15）含有与下部电极（12）的金属不同的金属和/或其氧化物作为主要成分，而且包含孔（152）。
Abstract(English):

A layered component (1) is provided with a ceramic substrate (11), a piezoelectric element (10), and an intermediate layer (15). The piezoelectric element (10) has a lower electrode (12). The intermediate layer (15) is formed between the substrate (11) and the lower electrode (12) of the piezoelectric element (10). The intermediate layer (15) contains as the principal component a metal different from the metal of the lower electrode (12) and/or an oxide thereof; and further includes a hole (152).
