PPROBLEM TO BE SOLVED: To provide a ferroelectric material for forming a ferroelectric film having hysteresis characteristic excellent in squareness loop. PSOLUTION: The ferroelectric material contains an A-site compensation component which compensates for a vacancy of an A site, and a B-site compensation component which compensates for a vacancy of a B site in a raw material liquid of a composite oxide described by the formula ABOSB3/SB.
