摘要

PROBLEM TO BE SOLVED: To provide a rubber/cord composite body that sufficiently secures adhesiveness between a steel cord and rubber even though using NS, TBSI and BEHZ as a vulcanization accelerator.SOLUTION: In a rubber/cord composite body 9 which comprises a steel cord made of a plated wire and rubber, the plated wire has a ternary plating layer that is formed of copper, zinc and cobalt and provided on a surface of a core wire. A composition in a surface region of the plating in the ternary plating layer includes 64-68 at% copper and 0.5-7.0 at% cobalt. The rubber contains the vulcanization accelerator that is formed of one substance selected from NS, TBSI and BEHZ or a substance obtained by combining two or more of them.
