Provided is a rubber analysis method in which an analysis of natural rubber and/or a diene-based synthetic rubber including an ultra-high molecular weight component which could not be analyzed in a conventional method. The method is a rubber analysis method comprising: a dissolution process in which natural rubber and/or diene-based synthetic rubber is/are dissolved in an organic solvent; and a separation process in which a solution in which the natural rubber and/or diene-based synthetic rubber is/are dissolved is subjected to a centrifugation at a centrifugal acceleration of from 10,000 G to 1,000,000 G, to separate a soluble component and an insoluble component in the solution.
