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.
Claims20
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.
1 more element
A method for producing a linear shape member, the method 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.

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

A method for producing a linear shape member, the method 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
