PROBLEM TO BE SOLVED: To provide an acrylic rubber composition excellent in physical properties in a normal state and characteristics of permanent compression set and decreased in rates of changes in tensile strength and elongation, when the composition is formed into a vulcanized material and the tensile strength and elongation are measured before and after heat treatment and compared, to provide the vulcanized material, to provide a hose component given by using the material, to provide a seal component, and to provide a vibration-isolation rubber component. SOLUTION: This acrylic rubber composition contains a carboxy group-containing acrylic rubber in an amount of 100 pts.wt., a guanidine compound in an amount of 0.1-10 pts.wt., a diamine compound in an amount of 0.01-10 pts.wt., and a polyfunctional monomer in an amount of 0.05-10 pts.wt.
