[Technical field] The present invention relates to a tool for attaching live bait such as earthworms to a fishing hook in angling. [Problem] The present invention provides a means for easily attaching live earthworms, etc., to a fishing hook without direct contact with a finger. [Solution] A bait-attaching tool characterized in that: a main body board is provided with a single hollow tunnel-shaped pathway having a diameter substantially equal to that of live bait such as earthworms a suction port for suctioning in the earthworms, etc., is provided at one end of the pathway, and an air discharge port is provided at the other end of the pathway the air discharge port is linked to a pump part connected to the main body board the pathway curves along the shape of a fishing hook the curved part is provided with a hook-holding part for holding the fishing hook so that the axial centers of the point, the barb portion, the point-side of the bend, and the shank-side of the bend of the fishing hook are positioned at the center of the diameter of the hollow of the pathway and so as to point towards the suction port the portion of the main body board from the suction port to the curved part opens and closes together with the opening and closing of an opening/closing lid and when the opening/closing lid is closed, the bait-attaching tool is sealed other than at the suction port and the air discharge port. [Usage] The bait-attaching tool is used to attach live bait such as earthworms to a fishing hook in angling.La présente invention concerne un outil permettant de fixer un appât vivant tel que des vers de terre à un hameçon de pêche à la ligne.
