A mirror structure and an optical scanner having the same which may achieve a high resolution since dynamic deformation is small while having a large driving angle. A plurality of vertical ribs are formed in a rear of the mirror of a scanner that reflects light, and are vertical to a torsional axis which is a center of vibration of the mirror. A horizontal rib is spaced apart from the torsional axis by a predetermined distance, and vertical to the vertical ribs. Optimum design parameters such as a size of the mirror, a moment of inertia, a driving angle, and dynamic deformation which are relevant to each other may be derived. Accordingly, the mirror may rotate at high speed and emit an image signal to a precise location.
