To reduce cost by eliminating the need to arrange a plurality of traverse detection sections, in a yarn winding device where drive of a package and a traverse of a yarn are independent of each other.

The yarn winding device 100 includes: a winding section 200 for winding a package 83; a traverse guide 17, driven independent from drive of the package 83, for traversing a yarn Y to be wound into the package 83; and a traverse detection section 70, arranged at a central part of a traverse width of the traverse guide 17, for detecting presence or absence of the yarn Y.
