A reclaimed rubber-containing rubber composition comprising a reclaimed rubber, wherein the reclaimed rubber allows a vulcanized rubber of a specific rubber composition for evaluation described below to have a rubber elastic modulus of 2.0 MPa or more as measured with an atomic force microscope:rubber composition for evaluation; a rubber composition containing 20 parts by mass of the reclaimed rubber per 100 parts by mass of isoprene rubber and not containing carbon black. The rubber composition for evaluation preferably contains 1.5 parts by mass of sulfur per 100 parts by mass of isoprene rubber. The reclaimed rubber-containing rubber composition preferably contains 1 to 10 parts by mass of the reclaimed rubber when a total amount of a rubber component is taken as 100 parts by mass.
