Rubber composition and method for producing the same
 The present invention provides a rubber composition containing a reclaimed rubber and a method for producing the same. A rubber molded article having excellent rubber properties can be obtained and the recycling of a used rubber product can be promoted by the present invention. A rubber composition of the present invention is a blend comprising a claimed rubber obtained by applying a heat and a shear stress to a vulcanized rubber, a non-vulcanized virgin rubber or/and a thermoplastic resin, wherein the reclaimed rubber contains 40% by weight or more of a residual toluene-insoluble gel component and the network chain density of the rubber in the gel component is 1/20 to 1/4 based on the network chain density of the rubber of the vulcanized rubber.
