A LiCoO 2 film-forming precursor solution is a precursor solution used to form a LiCoO 2 film which is used as a positive electrode material of a thin film lithium secondary battery. In this LiCoO 2 film-forming precursor solution, an organic lithium compound and an organic cobalt compound are dissolved in an organic solvent. In addition, the organic lithium compound is a lithium salt of a carboxylic acid represented by a formula C n H 2n+1 COOH (wherein, 2≦n≦8). |
