The present invention is drawn to a raw material for chemical deposition for producing a ruthenium thin film or a ruthenium compound thin film by a chemical deposition method, containing an organoruthenium compound represented by the following formula 1, and further containing -diketone that is the same as a ligand of the organoruthenium compound. The raw material for chemical deposition of the present invention is inhibited in discoloration/precipitation even when heated at a high temperature, and enables to form a stable ruthenium thin film or ruthenium compound thin film.
