An acupuncture tool for performing acupuncture includes an injection needle and an implant thread. The implant thread has one end side being inserted into a pore at a tip side of the injection needle and another end side being drawn so that when the injection needle is inserted into a body, the implant thread is also simultaneously implanted in the body and the injection needle is then extracted with the implant thread left in the body. The injection needle has a predetermined fastener movably mounted thereon. The fastener holds the other end side of the implant thread along the injection needle, and is configured to move in a direction reverse to a direction of inserting the injection needle while the fastener is holding the implant thread during a period from when the injection needle is inserted into the body to when the implant thread is implanted in the body.
