An iridium complex reagent for detecting oxygen concentration is provided. The iridium complex includes bis [1- (2′-benzothienyl) -quinolinato-N, C3 ′] iridium, bis [9- (2′-benzothienyl) -phenanthrinato-N, C3 ′. Coordination selected from iridium, bis [2- (2′-benzothienyl) -quinolinato-N, C3 ′] iridium, bis [2- (2′-benzothienyl) -pyridinate-N, C3 ′] iridium, and the like It consists of a compound containing an acetylacetone auxiliary ligand to which a body and a peptide residue are bound.
