The present invention provides a vulcanizate capable of reducing heat generation by a simpler method without depending on a specific rubber composition, a vulcanization system and compounding components, and a method for producing the vulcanizate. First, an unvulcanized rubber composition containing at least natural rubber and / or synthetic rubber and a filler is vulcanized and molded, and is obtained by a method defined in JIS K6300-2: 2001. obtaining a semi-vulcanized molding of vulcanization properties value is in the range of t 10 ~t 80. Next, the semi-vulcanized molded body obtained by the semi-vulcanized molding step is vulcanized again in a state where it is entirely deformed, and then the deformation is released to obtain a vulcanized product having a desired shape.
