An optical fiber cutting device provided with a speed reducing part which transmits drive force by reducing the drive speed of the external drive force, a drive force transmission part which transmits the drive force from the speed reduction part to the cutting blade holder, a cutting blade holder, a cutting blade which is held by the cutting blade holder and moves to the cutting position along with said cutting blade holder, and an optical fiber supporter which supports the optical fiber so as to be perpendicular to said cutting blade at the cutting position. In addition, when a cutting blade with a blade thickness alpha (mm) is used, and said cutting blade is moved at a speed beta (mm/minute) during cutting, alpha and beta fulfill the expression beta<=-253alpha+65.
