Provided is a fishing reel with movable magnet brake using a centrifugal force, the fishing reel including operation arms hinged in a spool and being rotated by a centrifugal force due to rotation of the spool, and a pad holder coupled to be able to move forward and backward in the longitudinal direction of a spool shaft and having a brake pad receiving attraction of a braking magnet, in which forward and backward positions of the pad holder are changed and the distance between the braking magnet and the brake pad is adjusted in accordance with a rotational angle of the operation arms due to a centrifugal force, whereby the braking force of the magnet brake decreases.
