    • A needle threader includes a flat handle portion and a thread-introducing loop portion extending from the handle portion. The thread-introducing loop portion includes a folded insertion edge at a tip for insertion into an eye of a needle. The thread-introducing loop portion includes a plate member having a first end, a second end, and a narrow band portion integrally connecting between the first and second ends. The narrow band portion has the folded insertion edge at a lengthwise center. The first end and the second end of the plate member are laid one on another and held in the handle portion. The narrow band portion is exposed from the handle portion to form the thread-introducing loop portion.
