An energy ray-curable elastomer composition, which comprises an energy ray-curable compound (A) having a (meth)acryloyl group, a polythiol compound (B) having 2 to 6 mercapto groups per molecule, and a polyfunctional (meth)acrylate (C), characterized in that the ratio of the number of (meth)acryloyl functional groups in component (A) to the number of mercapto functional groups in component (B) is 100:0.1-100:5n (wherein n represents the number of mercapto groups per molecule of the polythiol compound), and component (C) is used at a ratio of 1-8 parts by mass per 100 parts by mass of component (A). Thus, an energy ray-curable elastomer composition, which can achieve both high breaking elongation and good processability and shows good compression set, can be provided. |
