A fishing reel is provided which is capable of preventing noise and rapid change in the rotational speed of the spool which take place when a casting operation is performed, controlling backlash of a fishing line by a person even if the person is not skilled in the casting operation and maintaining the distance for which the tackle can be thrown. The fishing reel having a reel body 12 having a clutch-equipped rotational-force transmission means 20 for selecting a spool free state in which the free rotation of the spool is permitted and unreeling of the fishing line is permitted and or spool operation state in which the spool is rotated and the spool winds the fishing line; a conductive member 14 provided for the spool; magnets 16 for supplying magnetic force to the conductive member provided for the reel body 12 to brake the rotation of the spool; and a spool rotational-speed control means 26 for enlarging/reducing the magnetic force of the magnets which acts on the conductive member in accordance with the rotational speed of the spool so as to control the rotational speed of the spool.
