摘要

A ferroelectric element manufacturing method includes the steps of forming a buffer layer, which also functions as a sacrificial layer, on a single crystal substrate, forming a ferroelectric film on the buffer layer, separating the ferroelectric film and the single crystal substrate, and arranging the ferroelectric film that was separated from the single crystal substrate on an optional substrate.
