A slingshot for use in shooting a fish line comprises a Y-shaped body having two arms, each of which is provided with a safety pin and an upper tip to which an end of an elastic band is fastened. The elastic band is provided at the midpoint thereof with a leather piece attached firmed, thereto. The Y-shaped body further has a bottom end fastened to a fastener which is in turn fastened to a fishing rod. The bottom end of the Y-shaped body is fastened to the fastener in a manner that the Y-shaped body can be so adjusted as to be placed in a position perpendicular to the fishing rod or in a position in which the Y-shaped body rests on the fishing rod. With the slingshot, an angler is able to hurl out a fish line, along with a fishhook, a sinker and a float, to hit an intended area of the water surface.
