PROBLEM TO BE SOLVED: To provide a metal jig formed of integrated metallic materials used as artificial bait in water, which is effective as artificial bait in which a cavity is provided inside of the metal jig and buoyant materials are contained, and therefore a conventionally not existing buoyancy is added as an external force other than the resistance of water by the dead weight and an external shape, and an effective operation is performed by the fall and rise of the metal jig in water, and in addition to this, an operation in a resting state hardly operated until now is enabled.SOLUTION: A metal jig includes a body 1 formed of metallic members comprising lead and iron, tungsten or alloy thereof, and the inside of the body 1 is provided with a cavity 2. The metal jig contains the members having density smaller than water such as air or urethane foam as buoyant materials 3 in the cavity 2, and is sealed with the metallic members forming the body 1. A fishing line 5 is connected to an eye 4 projecting in the head side of the body 1 and used. |
