Claim:
1. A cutting device for cutting an optical fiber by applying a tension in a longitudinal direction of the optical fiber, the cutting device comprising: a single supporting piece having a free end and a fixed end and having resilience, the free end of the supporting piece being connected to a blade holder; a cutting blade held into the blade holder on the free end of the supporting piece; and a driving device having a plunger, the driving device being so disposed that the direction in which the plunger makes linear motion is in a plane perpendicular to, and does not intersect with, the direction in which the optical fiber runs, and configured to make the plunger advance to press the cutting blade, thereby the cutting blade supported by the supporting piece coming in contact with the optical fiber to make a right angle with the optical fiber, the plunger further pressing the cutting blade after coming in contact so that a pressing force generates a moment of the force about the contact point, thereby giving rotation moment to the cutting blade about the contact point and such that the cutting blade does not cut into the optical fiber deeper, and instead goes around the periphery of the optical fiber.
