MANUFACTURING METHOD OF MAGNETIC SHEET AND MAGNETIC SHEET

摘要

PROBLEM TO BE SOLVED: To manufacture an extremely high-quality magnetic sheet by reducing a change in thickness due to aging.

SOLUTION: When the magnetic sheet 10 formed by using a magnetic painting which is made by mixing at least the magnetic material with a polymeric binder dissolved in a solvent is pressed and compressed with using predetermined press plates 20, 21 in manufacturing the magnetic sheet, ventilation materials 30, 31 having Bekk smoothness of 150 sec/ml or less are interposed between at least the press plates 20, 21 and the one side surface of the magnetic sheet 10.
