PURPOSE: To increase the sensitivity and also, to reduce demagnetization factor by constituting a substrate of a flexible substance, and making the magnetic substance of amorphous metallic glass which has high characteristic permeability and is small in magnetic strain and low in saturation coercive force, and furthermore, specifying the thickness of the above magnetic substance. CONSTITUTION: A magnetic device has face material 1 which is bonded to a polymeric substrate 4, bearing the film of an amorphous metallic glass 3 by means of an adhesive thin layer 2. A band of a substance 6 for deactivation, fixed to the substrate 4 by another adhesive layer 5 exists under the substrate. A non-adhesive lining material sheet 8 is fixed to the element 6 for deactivation by another adhesive film 7. The form of the substance for deactivation is a needle-form steel substance, steel wool, needle-shaped substances lying on top of one another, or the like. A substrate 4 is a flexible laminated substance, and is made of polyamide or polyimide. The magnetic substance is metallic glass 3 which has high a characteristic permeability and is small in magnetic strain and further is low in saturation coercive force, and it is an alloy which contains cobalt, niobium, etc., together with glass formative element. The thin film of the above magnetic substance has a thickness not larger than 6 micron. |
