A fishing reel includes a handle, a spool on which a fishing line is wound, a partially open reel body housing an internal mechanism converting a rotational force applied to the handle into a movement to wind the fishing line onto the spool, a lid member closing the opening of the reel body, and a seal member disposed between an opening edge portion of the reel body and a lid flat surface of the lid member. The seal member includes a shape-retaining portion that holds the shape and a sealing material that has elasticity.
