Abstract: By laminating soft magnetic sheets 1, 11, a laminated soft magnetic member 5 in which insulating layers and soft magnetic metal layers are alternately laminated is produced. In this case, prior to laminating the obtained soft magnetic sheets 1, 11, or posterior to obtaining the laminated soft magnetic member 5 by laminating the soft magnetic sheets 1, 11, heat treatment is conducted under the conditions predetermined depending on the purpose of the heat treatment. During the heat treatment, pressing treatment can also be conducted concurrently. Additionally, when the heat treatment is conducted under the condition in which a tension is applied, further improvement of the magnetic properties can be expected.

Abstract: A laminated soft magnetic member 5, which comprises a laminated body in which 1 &mgr;m or less thick soft magnetic metal layer 7 and an insulating layer 6 are laminated alternately and is 0.2 mm or less in overall thickness, is excellent in permeability in the high frequency band exceeding 800 MHz, and accordingly, by being attached to a cellular phone, can improve the radiation efficiency of the electromagnetic wave on the side opposite to the head of a human body and is preferable as a member for the countermeasure against SAR.

Abstract: There is provided a soft magnetic member comprising a resin film 2, a metal sublayer 3 formed on the resin film 2 and a soft magnetic metal layer 4a formed on the metal sublayer 3. In the soft magnetic metal layer 4a, on the side of the metal sublayer 3, there is formed a region having a higher Fe concentration and a higher saturation flux density than other regions.
