摘要

The present invention provides a board for an electronic device, by which the electronic device with various excellent characteristics can be realized in the most suitable structure, an electronic device having such a board for the electronic device, a ferroelectric memory comprising such an electronic device, an electronic apparatus comprising the electronic device, ink-jet recording head comprising the electronic device, and an ink-jet printer having the electronic device.The board (100) for the electronic device comprises a substrate (11) having an amorphous layer (15), a buffer layer (12) formed on the amorphous layer (15), the buffer layer (12) having an orientation at least in the direction of its thickness, and a conductive oxide layer (13) formed on the buffer layer (12) by means of epitaxial growth, the conductive oxide layer (13) having a metal oxide of a perovskite structure. The buffer layer (12) contains at least one selected from the group consisting of a metal oxide of a NaCl structure and a metal oxide of a fluorite structure. Furthermore, the buffer layer (12) is formed by epitaxial growth in the cubic crystal (100) orientation.
