To provide a rubber composition for coating a steel cord, which serves as a raw material of a pneumatic tire excellent in balance between rubber hardness and elongation of a rubber part constituting a steel cord constituting a belt.SOLUTION: The rubber composition for coating a steel cord contains a rubber component, a filler, and a layered or plate-like mineral having an aspect ratio of 5 or more. When the content of the filler is 100, the content of the mineral is 1-10. When the total amount of the rubber component is 100 pts.mass, the content of the mineral is preferably 4.5 pts.mass or less. The aspect ratio of the mineral is preferably 100 or more.SELECTED DRAWING: None
