A method of aligning a fiber collimator in a short time. Light emitted from a collimator is reflected by a mirror. Reflected light passes through the collimator, and is measured by a light intensity measuring device. Rotating bodies rotatably support the mirror about an X-axis and a Y-axis orthogonal to the optical axis. An aligner simultaneously drives the rotating bodies to scan an optimal angle for the mirror. With the mirror fixed at the optimal angle, the distance between a collimation lens of the collimator and the optical fiber is changed. Subsequently, the optimal angle of the mirror is again scanned.
