The fishing reel includes a spool 5A rotatably supported between side plates of a reel body 2, and a level wind device 50 with a fishing line guide body 60 configured to thread a fishing line unreeled from the spool 5A and reciprocate between the right and left side plates. The fishing line guide body 60 is supported in front of the spool and switchable between fishing line winding/unwinding states, and includes a fishing line guide section 67 for guiding the fishing line to the spool in the winding state and having a narrow width in the right and left direction, an opening 68 to reduce resistance against unwinding line in the unwinding state and having a wide width in the right and left direction, and a regulator 69 configured to prevent the fishing line from slipping out of the fishing line guide section in the winding state.
