LAYERED COMPONENTS AND METHOD FOR PRODUCING SAME

摘要

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).
