To provide a rubber crosslinked article excellent in wet grip property, low heat generation property and abrasion resistance.SOLUTION: There is provided a rubber crosslinked article by crosslinking a rubber composition containing a conjugated diene rubber and an inorganic filler, in which a ratio between loss tangent value of a non-boundary surface component forming a part other than a boundary surface with the inorganic filler K(m) in a crosslinked rubber component, and loss tangent value K(i) of a boundary surface component forming the boundary surface with the inorganic filler in the crosslinked rubber component, K(i)/K(m) is 0.80 or less when loss tangent is measured by using atomic force microscope in a state where vibration with 10 Hz of sine wave is added to the rubber crosslinked article.SELECTED DRAWING: None

    【課題】ウエットグリップ性、低発熱性および耐摩耗性に優れたゴム架橋物を提供すること。【解決手段】共役ジエン系ゴムと、無機充填剤とを含有するゴム組成物を架橋してなるゴム架橋物であって、前記ゴム架橋物に対し、10Hzの正弦波による振動を与えた状態にて、原子間力顕微鏡を用いて損失正接を測定した際における、架橋ゴム成分のうち、前記無機充填剤との界面以外の部分を形成する非界面成分の損失正接値K(m)と、架橋ゴム成分のうち、前記無機充填剤との界面を形成する界面成分の損失正接値K(i)との比K(i)/K(m)が0.80以下であることを特徴とするゴム架橋物を提供する。【選択図】なし
