(57) [Problem] To provide a bismuth lanthanum titanate (BLT) represented by the following general formula (1), a BLT thin film, a production method thereof, and an electronic element using the BLT thin film. SOLUTION: BLT represented by the following general formula (1) is manufactured in the form of a thin film, and even if only a metal electrode is laminated on the upper and lower parts thereof, a fatigue phenomenon is extremely unlikely to occur, the reliability is excellent, and the capacity is high. Can be manufactured. Such a capacitor can be applied to various electronic devices such as a FeRAM device and a pyroelectric sensor. Bi 4 −x La x Ti 3 O 12 (1) In the general formula (1), 0 <x ≦ 2. |
