This cemented carbide composite roll is characterized by being formed from a steel inner layer, an intermediate layer made from a cemented carbide containing WC particles, and an outer layer, wherein the cemented carbide configuring the outer layer contains 55-90 parts by mass of WC particles and 10-45 parts by mass of a binder phase that has a specific composition with Fe as the main component, the cemented carbide configuring the intermediate layer contains 30-65 parts by mass of WC particles and 35-70 parts by mass of a binder phase that has a specific composition with Fe as the main component, and, when defining c1 as the content of WC particles in parts by mass in the outer layer and c2 as the content of WC particles in parts by mass in the intermediate layer, it holds that 0.45 ≤ c2/c1 ≤ 0.85.
