An analysis method for a rubber composition includes the followings: (1) acquiring input data generated from a microscopic image obtained by image-capturing a rubber composition with a microscope, the microscopic image showing a formulation contained in the rubber composition; (2) inputting the input data to a trained machine learning model; and (3) deriving output data from the trained machine learning model. The output data is data defining a region that appears in the microscopic image corresponding to the formulation.
