<P>PROBLEM TO BE SOLVED: To provide a board for an electronic device, by which the electronic device with various excellent characteristics is achieved in the most suitable structure, an electronic device having such board for the electronic device, a ferroelectric memory comprising such an electronic device, an electronic apparatus comprising the electronic device, inkjet recording head comprising the electronic device, and an inkjet printer having the electronic device. <P>SOLUTION: 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 preferably contains at least one selected from a metal oxide of the NaCl structure and a metal oxide of the fluorite structure. Furthermore, the buffer layer 12 is preferably formed by epitaxial growth in the cubic crystal (100) orientation. <P>COPYRIGHT: (C)2009,JPO&INPIT |
