To provide a vulcanized rubber-metal complex that excels in crack resistance, low pyrogenicity, and adhesion between vulcanized rubber and metal, and a tire that comprises the vulcanized rubber-metal complex and excels in durability, a hose, and a crawler.SOLUTION: A vulcanized rubber-metal complex comprises a metal, and a vulcanized rubber that coats the metal. The vulcanized rubber is a vulcanized rubber of a rubber composition that comprises a rubber component, carbon black, and silica, with a content of a cobalt-containing compound being 0.01 pts.mass or less being relative to 100 pts.mass of the rubber component. In the rubber composition, the content of the cobalt-containing compound is 0.01 pts.mass or less being relative to 100 pts.mass of the rubber component. The metal is a metal having a steel cord surface being coated with ternary plating of copper, zinc, and iron.SELECTED DRAWING: None
