PROBLEM TO BE SOLVED: To provide a rubber molding having the on-ice performance improved compared to the conventional level.SOLUTION: A rubber molding has a region A and a region B differing in surface free energy provided independently on its surface. An absolute value of the difference between a surface free energy of the region A and a surface free energy of the region B is 0.4 dyne/cm or more, and a ratio Sa/Sb between an area Sa of the region A and an area Sb of the region B is 10/90-90/10.SELECTED DRAWING: None

    【課題】氷上性能を従来レベル以上に向上するようにしたゴム成形体を提供する。【解決手段】ゴム成形体の表面に表面自由エネルギーが相違する領域Aおよび領域Bを互いに独立して有し、該領域Aの表面自由エネルギーおよび領域Bの表面自由エネルギーの差の絶対値が0.4dyne/cm以上、かつ前記領域Aの面積Saおよび領域Bの面積Sbの比Sa/Sbが10/90〜90/10であることを特徴とする。【選択図】なし
