The one-handed needle having a simple manufacturing process and improved productivity is started. The one-handed needle of the present invention has a plate-shaped handle portion having a thickness formed with an insertion groove on the front surface thereof; A recess formed in the insertion groove and extending in the longitudinal direction; And a pointed portion that can be inserted into the human body by an inclined portion inclined toward the tip at the other end of the stagnation. According to the present invention, it is possible to simultaneously form the insertion hole in which the stagnation is inserted in the grip portion of the one-handed needle in the molding process of the grip portion, thereby saving cost and time. It is possible to effectively prevent slippage and to increase the accuracy and reliability of the procedure.
