The present invention is directed to a fishing reel. The fishing reel comprises a reel body (1), a housing part (4) including an opening part, a driving member including a pinion (3) that is rotatably supported by the reel body (1) and extends through the opening part of the housing part (4), and a magnetic seal device affixed to the housing part (4) and including a central opening through which the pinion (3) extends. The magnetic seal device includes a magnet (8), first and second magnetic plates (9a, 9b) securing the magnet (8) therebetween and a magnetic fluid (10) that is maintained at a gap between the driving member and at least one of the first and second magnetic plates (9a, 9b). The fishing reel is characterized in that an external diameter of the first magnetic plate (9a) is larger than an external diameter of the second magnetic plate (9b).
