Abstract: A coating removal blade used in an optical fiber coating removal apparatus that removes a coating material of an optical fiber includes a blade tip that is pressed against the coating material from a radial direction of an optical fiber bare wire of the optical fiber, and a pressing surface against which the coating material to be pulled out from the optical fiber is pressed in a longitudinal direction of the optical fiber. The pressing surface includes an inclined surface that is inclined at a constant angle to extend in a direction opposite to a pulling-out direction of the optical fiber as a distance from the blade tip in the radial direction of the optical fiber bare wire increases, and an inclination angle of the inclined surface with respect to the pulling-out direction of the optical fiber is larger than 0° and equal to or smaller than 60°.

Abstract: A coating removing device includes a main body that includes a blade used for coating removal; a gripping section that grips an optical fiber; and a slider that connects the main body and the gripping section together so as to be able to approach or separate from each other. The coating removing device removes a coating from the optical fiber by separating the main body and the gripping section after an incision has been made in the coating of the optical fiber using the blade. The slider includes a retention unit to retain the main body and the gripping section in a maximum separation state.
