摘要
The present invention relates to a composite magnetic sheet having improved permeability, a manufacturing method thereof, and an electromagnetic wave absorber using the same. According to the present invention, the method for manufacturing a sheet comprises the steps of: (i) preparing a mixture of powder and a binder; (ii) preparing a supporter; (iii) forming a sheet with the mixture of the powder and the binder on the supporter; (iv) winding the sheet in a roll shape which is generated on the supporter by applying tension to the supporter; and (v) heat-processing the sheet formed on the supporter which is wound in the roll shape with tension applied. The manufacturing method can freely obtain the shape and the size of the sheet according to the shape and the size of a sheet which is needed in the following process.
