SOFT MAGNETIC SHEET

摘要

A soft magnetic sheet produced using a polyester resin having satisfactory processability. It has a satisfactory appearance having no marks at which air has erupted upon high compression. Particles which are incompatible with the polyester resin are added. Due to the particles dispersed in the polyester resin, a soft magnetic sheet having a smooth surface is formed. Because of the surface smoothness, the amount of air included during stacking and compression is small. Consequently, even when the stack is compressed at a high pressure in order to heighten the specific gravity, no air eruption marks result and a satisfactory appearance can be obtained. Compressing at a high pressure enables soft magnetic particles to be compacted densely. Thus, a soft magnetic sheet having satisfactory magnetic properties is obtained.
