LAYERED COMPONENTS AND METHOD FOR PRODUCING SAME

摘要

A laminate (1) includes a ceramic substrate (11), a piezoelectric element (10), and an intermediate layer (15). The piezoelectric element (10) includes 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 a metal or an oxide thereof as a main component. The metal is different from a metal contained in the lower electrode (12). The intermediate layer further contains holes (152).
