摘要： There are provided an optical fiber cutting method and a cutting apparatus which can easily cut a coated optical fiber without a step of removing a coating from the optical fiber. It includes a clamp which holds the coated optical fiber, having a glass fiber and the coating, on both sides of a portion-to-be-cut, a disk-shaped blade member which moves at the portion-to-be-cut in a direction orthogonal to an axis of the optical fiber to cut the coating and to provide a slit into the glass fiber, and a support which presses, with a predetermined pressing force, the portion-to-be-cut from an opposite side of the blade member with respect to the portion-to-be-cut when cutting the coating and providing the slit into the glass fiber. A head of the support is formed with a groove along a sliding direction of the blade member.
