The technological purpose of the present invention is to provide a device for thread embedding therapy which can prevent an embedded thread winding unit from loosening while a needle is inserted into skin tissue. The device for thread embedding therapy includes: an embedded thread; and the needle in the shape of a tube which has an inner path that the embedded thread penetrates. A through-hole, communicating with the inner path, is formed on a circumferential side of a tip of the needle. The embedded thread is inserted into the through-hole. A first portion of the embedded thread penetrates the inner path. A second portion of the embedded thread is wound in a spiral shape on an outer circumferential side of the needle. A portion of the embedded thread between the first portion and the second portion is located in the through-hole.
