Abstract

A linear shape member is composed of a linear shape electrical insulating body comprising irregularities on a surface, and a plating layer coating the surface of the electrical insulating body. An average irregularities spacing Sm of the irregularities is not more than 20.0 μm.

First claim

What is claimed is:

1 . A linear shape member, comprising:
a linear shape electrical insulating body comprising irregularities on a surface; and a plating layer coating the surface of the electrical insulating body, wherein an average irregularities spacing Sm of the irregularities is not more than 20.0 μm.

2 . The linear shape member according to claim 1 , further comprising:
a linear shape conductor, with the electrical insulating body coating a periphery of that linear shape conductor, wherein the plating layer acts as a shield.

3 . A method for producing a linear shape member, comprising:
performing a roughening treatment on a surface of a linear shape electrical insulating body; and after the roughening treatment, performing a plating treatment on the surface of the electrical insulating body to form a plating layer thereon, wherein the roughening treatment allows an average irregularities spacing Sm of the irregularities to be reduced to not more than 20.0 μm.

4 . The linear shape member producing method according to claim 3 , wherein the roughening treatment is performed by a blasting treatment.

5 . A linear shape member, comprising:
a linear shape electrical insulating body; and a plating layer coating a surface of the electrical insulating body, wherein, within a region of a depth of up to 1 μm from the surface of the electrical insulating body, a degree of crystallization, Xc, represented by equation 1 below is not lower than 0.512 and not higher than 0.685, where Ic in the equation 1 denotes an absorption peak intensity of a crystalline component in a Fourier transform infrared absorption spectrum in the electrical insulating body, while Ia in the equation 1 denotes an absorption peak intensity of an amorphous component in the Fourier transform infrared absorption spectrum in the electrical insulating body.

6 . The linear shape member according to claim 5 , wherein the electrical insulating body comprises a polyethylene.

7 . The linear shape member according to claim 5 , further comprising:
a linear shape conductor, with the electrical insulating body coating a periphery of that linear shape conductor, wherein the plating layer acts as a shield.

8 . A method for producing a linear shape member, comprising:
performing a modification treatment on a surface of a linear shape electrical insulating body; and after the modification treatment, performing a plating treatment on the surface of the electrical insulating body to form a plating layer thereon, wherein the modification treatment allows a degree of crystallization, Xc, represented by equation 2 below within a region of a depth of up to 1 μm from the surface of the electrical insulating body to be increased to within a range of not lower than 0.512 and not higher than 0.685, where Ic in the equation 2 denotes an absorption peak intensity of a crystalline component in a Fourier transform infrared absorption spectrum in the electrical insulating body, while Ia in the equation 2 denotes an absorption peak intensity of an amorphous component in the Fourier transform infrared absorption spectrum in the electrical insulating body.
