Title:
LAMINATE
Document Type and Number:
Japanese Patent JP2007221869
Kind Code:
A
Abstract:

To provide a laminate, employing a soft magnetic alloy thin band principally comprising Fe and exhibiting high saturation flux density, high initial relative permeability, and low coercive force.

In the laminate, obtained by bonding a plurality of sheets of soft magnetic alloy thin band principally comprising Fe and having a thickness of 50 μm or smaller, the density is 6.2 g/cm3or higher, the saturation flux density is 1.42T or higher, and the coercive force is 10 A/m or smaller. Flux density B8000in application magnetic field 8000 A/m can be made 1.4T or higher.
