Abstract: Provides a method and a terminus processing tool whereby terminus processing for the purpose of connection to another optical fiber may be carried out simply. The terminus processing method entails cutting an optical fiber 20 composed of a glass fiber 21 and a coating 24; and with the optical fiber 20 positioned relative to a terminus processing tool that is disposed contacting the coating at the end surface of the optical fiber 20 and that has a protruded-into space for accommodating inward protrusion of the glass fiber 21, and with the cut end surface of the glass fiber 21 facing the protruded-into space, pushing the optical fiber 20 to thereby strip the coating 24 from the glass fiber 21.
