BODY WITH MAGNETIC FILM ATTACHED AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2010/055597

A1

Provided is a manufacturing method for a body with a magnetic film attached where a magnetic film is affixed to a base. The manufacturing method comprises a step of preparing the base and a step of forming a magnetic film composed of alternate layers of organic film and ferrite film on the base. In the manufacturing method, the step of forming a magnetic film involves alternately performing a step of forming a ferrite film having a film thickness of no more than 20 μm by a ferrite plating method, and a step of forming an organic film having a film thickness of at least 0.1 μm and no more than 20 μm and a t/E ratio of the film thickness (t) to Young’s modulus (E) of the organic film of at least 0.025 μm/GPa.
