SOLUTION: cis-Ti (Ot-Bu) 2 (DP M) 2 : HD in an organic solvent solution of Ti (Ot-Bu) 4 Add PM and heat to reflux to cis-Ti (Ot-B u) 2 (DPM) 2 crystals are obtained. A liquid composition for forming a BST film, wherein this high-purity Ti complex and Ba (DPM) 2 and / or Sr (DPM) 2 are dissolved in an organic solvent. Embedded image [Effect] By the CVD method, it is possible to form a TiO film having good step coverage and high purity and excellent electric characteristics. A BST film having a desired film composition can be formed by the solution supply method.
