The organozirconium composite of the present invention has a decomposition temperature which is near the respective decomposition temperatures of an organolead compound and an organotitanium compound. The raw material solution can precisely control the composition of a PZT thin film over a broad temperature range. The raw material solution is less likely to react an organolead compound even when mixed with the organolead compound. The present invention provides a raw material solution which is less likely to cause vapor phase cracking. The organozirconium composite comprises one, or at least two kinds of zirconium chelate complexes containing, as a ligand, both of a first diketone and a second diketone having a structure different from that of the first diketone, wherein, when at least two kinds of zirconium chelate complexes are contained, the coordination numbers of the first diketone and the second diketone that coordinate to at least two kinds of zirconium chelate complexes vary depending on the respective zirconium chelate complexes.
