Abstract: Provided is a rubber composition capable of forming a conveyor belt having an excellent low loss property, while also retaining high strength and high flame retardance as a rubber article. The rubber composition for a conveyor belt contains: rubber components including natural rubber and butadiene rubber; a vulcanizing agent; a vulcanization accelerator; carbon black; chlorinated paraffin; and antimony trioxide. A mass ratio of content of the natural rubber to content of the butadiene rubber (natural rubber content:butadiene rubber content) is 25:75 to 45:55.
