Provided is a rubber composition for coating a metal cord that can achieve both crack resistance and low heat generation properties at a high level. The rubber composition for coating a metal cord contains a rubber component, carbon black having an adsorption specific surface area of cetyltrimethylammonium bromide (CTAB) of 110 m2/g to 160 m2/g, a half width ΔD50 of a peak including a Stokes equivalent diameter Dst that is the most frequent in an aggregate distribution obtained with a centrifugal sedimentation method of 60 nm or less, and a ratio of the ΔD50 to the Dst (ΔD50/Dst) of 0.95 or less, silica having a CTAB adsorption specific surface area of 200 m2/g or more, and a vulcanizing agent.
