Provided is a method of producing a rubber molded article, including crosslinking a rubber compound at a temperature lower than a usual crosslinking temperature (150° C. or more). The method includes a crosslinking step of crosslinking a rubber compound at a temperature of 100° C. or less, the rubber compound having a nitrile structure represented by the following formula (I) and an olefin structure represented by the following formula (II), in a rubber composition containing the rubber compound and a thiol compound having at least two thiol groups in a molecule thereof: provided that R in the formula (II) represents a divalent organic group having 4 or more carbon atoms and having an unsaturated bond represented by —C═C— in a structure thereof.
