To increase the number of fishes hooked up in a wide region from a sea bottom area to a shallow layer area from the surface of the sea and to avoid damage and fishline removal of fishing tool by making a circular drum imitate a winding speed which is supplied to a fishline by a deformed drum such as a rhombic drum, etc.

In the fishline winder 10 for winding a fishline 1 on the circular drum 12 driven by an electric motor 14, the fishline winder has a control means 20 for controlling the electric motor 14 so that the winding speed of the fishline 1 by the circular drum 12 is coincident with a winding speed which is supplied to the fishline 1 when the deformed drum 12A of an arbitrary shape rotates at a virtual rotational speed.
