PROBLEM TO BE SOLVED: To provide a crosslinked composition with less oil bleeding at high temperatures, and excellent in flexibility and heat resistance. SOLUTION: The crosslinked composition is obtained by crosslinking a composition containing (I) 100 pts.mass of a vinyl aromatic copolymer, (II) 10-100 pts.mass of an olefin resin, (III) >300 pts.mass and≤500 pts.mass of a softener, and (IV) 0.01-50 pts.mass of a crosslinker, wherein the vinyl aromatic copolymer (I) contains 5-70 mass% of a vinyl aromatic monomer unit and 0.1-20 mass% of a conjugated diene monomer unit, and hardness at room temperature (23°C) is≤40 A.
