A coating removal blade used in an optical fiber coating removal apparatus configured to remove 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, where the pressing surface includes an inclined surface inclined at a constant angle so as 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°.
