As a rubber composition excellent in fatigue resistance and a method for producing the same, this disclosure provides a rubber composition containing a zinc oxide, wherein: a total volume of aggregates of the zinc oxide with a diameter of 20 μm or more is 0.008 or less in the rubber composition by volume fraction; and a method for producing the rubber composition, comprising: preparing a wet masterbatch by using a carbon black with a surface average acidic functional group amount (μeq/m2) of 0.15 or more and less than 3.00, preferably 0.40 or more and less than 1.50; and compounding a zinc oxide with the wet masterbatch.
