Provided is a fishing reel provided with a fishing line guide body capable of effectively reducing unwinding resistance applied to a fishing line when the fishing line is unwound from a spool in a vertically undulating manner. The fishing reel includes a level wind device including a fishing line guide body (60) through which the fishing line (S) unreeled from the spool is threaded. The fishing line guide body (60) includes a fishing line threading section (60A) that forms an elongated opening (65) of which a height in a vertical direction is larger than a width in a left and right direction. The fishing line guide body (60) is rotated forward and the fishing line threading section (60A) stands up in the vertical direction during the unwinding of the fishing line. The fishing line guide body is rotated rearward and the fishing line threading section (60A) falls down during the winding of the fishing line, so that a fishing line guide section (70) comes into contact with the fishing line (S) threaded through the fishing line threading section (60A).
