The fishing reel includes a spool 5A rotatably supported between side plates of a reel body 2, and a level wind device 50 provided 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 a fishing line winding state and a fishing line unwinding state, and also includes a fishing line guide section 67 configured to guide the fishing line to the spool in the fishing line winding state and having a narrow width in the right and left direction, an opening 68 configured to reduce resistance against unwinding the fishing line in the fishing line 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 fishing line winding state.
