A production method for a separated fiber bundle includes at least: [A] a partial separation step for obtaining a partially separated fiber bundle in which separation-processed parts, each separated into a plurality of bundles, and not-separation-processed parts are alternately formed along the lengthwise direction of a fiber bundle comprising a plurality of single fibers; and [B] a cutting step for cutting the not-separation-processed parts of the partially separated fiber bundle formed in the step [A] along the lengthwise direction of the fiber bundle. A separated fiber bundle produced by the method, a fiber-reinforced resin molding material that uses the separated fiber bundle, and a production method for the fiber-reinforced resin molding material.
