Abstract: Provided is a ferrule polishing material suitable for polishing a ferrule. A ferrule polishing material of the present invention solving the above object includes a binder formed from a resin material and abrasive grains dispersed in the binder. The resin material is formed from an epoxy resin. The abrasive grains are contained in an amount of not less than 80% and not greater than 91% with respect to the sum of masses of the abrasive grains and the binder, include small-diameter particles being particles having a particle diameter of not greater than 100 nm, the small-diameter particles being present in an amount of not less than 62.5% and not greater than 80% with respect to the mass of the abrasive grains, and are formed from silica.
