A cord-rubber composite 11 comprises a cord array 12 of parallel steel cords 14, and an unvulcanized topping rubber 13 coating the cord array 12 and having a complex elastic modulus E* of not less than 5 MPa after vulcanization. The code array has a surface area parameter S (mm) of not less than 60 mm. The surface area parameter S (mm) is defined by the following expression: S = D x Pi x E, wherein E is a cord count of the steel cords 14 per 5 cm width of the cord-rubber composite 11 in a direction orthogonal to longitudinal directions of the steel cords, and D is an average outer diameter (mm) of the steel cords per the 5 cm width.
