Abstract

A DLC-coated fishing lure includes a fishing lure base material made of metal and having a predetermined shape; an intermediate layer made of one selected from a first group, a second group and a third group, the first group consisting of at least one kind of metal selected from the IIIb group, the IVa group, the Va group and the VIa group in the periodic table of elements, the second group consisting of at least one of a carbide, a nitride and a carbonitride of the at least one kind of metal, and the third group consisting of a mutual solid solution made of at least one selected from the first group and the second group, the intermediate layer being formed on a surface of the fishing lure base material; and a DLC layer having a thickness ranging from about 0.05 μm to about 0.55 μm and formed on the intermediate layer, the DLC layer presenting an appearance of a interference color.

Claims

1. A DLC-coated fishing lure comprising:

a fishing lure base material made of metal and having a predetermined shape;

an intermediate layer comprising at least one substance selected from;

a first group of substances consisting of metals of the IIIb group, the IVa group, the Va group, and the VIa group of the periodic table of elements,

a second group of substances consisting of carbides, nitrides, and carbon nitrides of the substances of the first group, and

a third group of substances consisting of mutual solid solutions comprising at least one substance selected from the first group and the second group,

the intermediate layer being formed on a surface of the fishing lure base material;

a DLC layer having a thickness ranging from about 0.05 μ

m to about 0.55 μ

m and formed on the intermediate layer, wherein

the DLC layer presents an appearance of an interference color, and

the thickness of the DLC layer smoothly varies within a width of about 0.05 μ

m or over; and

at least one through-hole in the fishing lure base material that accommodates a fishhook or a fishing line.

2. The fishing lure of claim 1, wherein the surface of the fishing lure base material has a smoothly bowed shape.

3. The fishing lure of claim 2, wherein a thickness of the intermediate layer ranges from about 0.5 μ

m to about 3 μ

m.

4. The fishing lure of claim 1, wherein a thickness of the intermediate layer ranges from about 0.5 μ

m to about 3 μ

m.

5. The fishing lure of claim 1, wherein the intermediate layer has a single-layer structure consisting of one kind of metal, and the DLC layer has a single-layer structure consisting of one kind of metal.
