PURPOSE: A holder for an optical fiber is provided to maximize an input amount of an optical fiber by moving the plane position of the optical fiber. CONSTITUTION: A moving plate(200) fixes an optical fiber. A support plate(100) forms a seating recess and two adjacent moving holes for inserting the moving plate. A position control member(160) is combined with moving hole, linearly moves, and controls the movement of the moving plate. An elastic bar(170) is inserted into the seating recess of the moving plate and supports the moving plate. Both ends of the elastic bar are inserted into a circle recess(150). A fixing plate(300) is closely adhered to the upper side of the support plate.
