PROBLEM TO BE SOLVED: To provide a cross-linked ethylene-propylene-diene copolymer composition capable of improving the degree of cross-linking even in the case of adding an organic filler treated with a surface-treating agent having a double bond at its terminal. SOLUTION: This cross-linked ethylene-propylene-diene cross-linked composition is provided by adding 100-200 pts.mass inorganic filler surface-treated with a surface-treating agent having the double bond at its terminal and 1.0-20 pts.mass dimethacrylate of chemical structural formula (1) as a cross-linking assistant based on 100 pts.mass ethylene-propylene-diene copolymer and being cross-linked by an organic peroxide. CH2=C(CH3)-COO-(CH2CH2O)n-[(C=O)-C(CH3)=CH2] (provided that n=1 to 30): chemical formula (1). COPYRIGHT: (C)2007,JPO&INPIT
