Claim:
1. A raw material for producing a ruthenium thin film or a ruthenium compound thin film by a chemical deposition method, and comprising a ruthenium complex, wherein the ruthenium complex is represented by the following formula, in which carbonyl groups and a fluoroalkyl derivative of a polyene are coordinated to ruthenium: wherein L is a polyene having a carbon number of from 4 to 8 and 2 to 4 double bonds, wherein the polyene L has n (n≧1) pieces of substituents R, wherein the substituents Rs are each a fluoroalkyl group having a carbon number of from 1 to 6 and a fluorine number of from 1 to 13, and in the case when the polyene L has two or more (n≧2) of the substituents Rs, the carbon numbers and the fluorine numbers of the substituents Rs may be different in the same molecule.
