Abstract
A fabrication method for fabricating a magnetic film provided body includes preparing a base body and forming a magnetic film on the base body. The magnetic film includes organic film(s) and ferrite film(s) alternately layered. The formation of the magnetic film alternately includes forming a ferrite film through a ferrite plating method, the ferrite film having a thickness of 20 μm or less, and forming an organic film having a thickness of 0.1 μm to 20 μm, both inclusive, and a ratio t/E of 0.025 μm/GPa or more, where “t” indicates the thickness of the organic film while “E” indicates Young's modulus of the organic film.

A fabrication method of a magnetic film provided body comprising:
- preparing a base body and forming a magnetic film on the base body, the magnetic film comprising at least one organic film and at least one ferrite film alternately layered,
- wherein the formation of the magnetic film alternately out comprises:
- forming a ferrite film through a ferrite plating method, the ferrite film having a thickness of 20 μm or less;
- and
- forming an organic film, the organic film having a thickness of 0.1 μm to 20 μm, both inclusive, the organic film having a ratio t/E of 0.025 μm/GPa or more, where “t” indicates the thickness of the organic film, and “E” indicates Young's modulus of the organic film.
A magnetic film provided body comprising:
- a base body;
- and
- a magnetic film provided on the base body,
- wherein:
- the magnetic film comprises at least one organic film and at least one ferrite film alternately layered;
- and
- an adhesive strength between the organic film and the ferrite film is 0.1 kN/m or more.
