    • In the needle thread wiper of sewing machine according to the invention, the hook formed at the front end of a leaf spring is projected in or out from the front end of the guide element formed nearly in a J-form, and when inserting this hook into the front end of the guide element, the needle threads extending between the needle and cloth is hooked on the front end of this hook so as to be placed into the front end of the guide element together with the hook. At the front end of the guide element, at the positions corresponding to the both flat surfaces of the leaf spring, notches are formed so as to extend from the front end to the base part side. The needle thread introduced into the front end of the guide element is guided by the notches and placed deeply into the guide element. The needle thread is held merely in a state of being hooked between the hook and the guide element, and so that is easily unhooked, almost without any resistance, when the needle is lowered upon start of next sewing step.
