To provide a rubber-metal composite in which a rubber and a zinc-plated member are highly bonded without using a cobalt-based compound which is widely used as a rubber-metal adhesion promoter.SOLUTION: There is provided a rubber-metal composite obtained by bringing a rubber composition and a metal member into contact with each other, wherein the metal member is subjected to zinc plating, the rubber composition comprises a metal salt (1) of a carboxylic acid having 2 to 25 carbon atoms in which the metal species is bismuth, antimony, niobium, silver or zirconium, at least one metal compound selected from compounds (2) represented by a predetermined general formula (A) and a chlorinated paraffin, the content of the metal compound is 1.4 pts.mass or more in terms of metal element of bismuth, antimony, niobium, silver and zirconium based on 100 pts.mass of the rubber component and the content of the chlorinated paraffin is 3 pts.mass or more based on 100 pts.mass of the rubber component.SELECTED DRAWING: None

    【課題】ゴム−金属間接着の促進剤として汎用されているコバルト系化合物を用いることなく、ゴムと亜鉛メッキ部材とが高度に接着された、ゴム−金属複合体を提供する。【解決手段】ゴム組成物と金属部材とが接触してなるゴム−金属複合体であって、前記金属部材は、亜鉛メッキが施されており、前記ゴム組成物は、炭素数が2〜25であり、金属種がビスマス、アンチモン、ニオブ、銀又はジルコニウムであるカルボン酸の金属塩(1)、及び、所定の一般式(A)で表される化合物(2)から選択される少なくとも1種の金属化合物と、塩素化パラフィンとを含有し、前記金属化合物の含有量が、ゴム成分100質量部に対し、ビスマス、アンチモン、ニオブ、銀及びジルコニウムの金属元素換算で1.4質量部以上であり、前記塩素化パラフィンの含有量が、ゴム成分100質量部に対して3質量部以上である、ことを特徴とする、ゴム−金属複合体。【選択図】なし
