摘要

PROBLEM TO BE SOLVED: To provide a soft magnetic thin wire used for a particular frequency region and superior in magnetic property, and a manufacturing method thereof; a mesh sheet for AC use, a sintered sheet for AC use, a rubber sheet for AC use, and a laminate sheet for AC use arranged by use of such a soft magnetic thin wire.SOLUTION: A soft magnetic thin wire comprises a soft magnetic material having a diameter of 0.15 mm or less, of which the crystal grains have a diameter within a range of 1-100 m, the areal percentage is 50% or more, the saturated magnetic flux density is 0.6-2.6 T, and the complex relative magnetic permeability is 100 or more at 125 kHz. A mesh sheet for AC use, a sintered sheet for AC use, a rubber sheet for AC use and a laminate sheet for AC use are produced by weaving and baking the soft magnetic thin wire, or compounding with a rubber or a resin.
