The present invention relates to a chemical deposition raw material for manufacturing an iridium thin film or an iridium compound thin film by a chemical deposition method, including an iridium complex in which cyclopropenyl or a derivative thereof and a carbonyl ligand are coordinated to iridium. The iridium complex that is applied in the present invention enables an iridium thin film to be manufactured even when a reducing gas such as hydrogen is applied. in which Rto R, which are substituents of the cyclopropenyl ligand, are each independently hydrogen, or a linear or branched alkyl group with a carbon number of 1 or more and 4 or less.
