PROBLEM TO BE SOLVED: To provide an acrylic elastomer composition comprising silica which improves extrudability and roll moldability without reducing its heat resistance. SOLUTION: The acrylic elastomer composition comprises (A) 100 pts.wt. acrylic elastomer, (B) 5-300 pts.wt. silica, and (C) 2-30 pts.wt. liquid paraffin, silicone oil or fluorine oil, and preferably further comprises (D) 0.1-5 pts.wt. silane coupling agent. In this acrylic elastomer composition, by using 2-30 pts.wt. liquid paraffin, silicone oil or fluorine oil per 100 pts.wt. acrylic elastomer, the extrudability and the roll moldability can be improved without reducing the inherent heat resistance of the acrylic elastomer, and consequently the ratio of other lubricants (processing aids) used such as stearic acid can be reduced.
