<P>PROBLEM TO BE SOLVED: To provide a laminate core having excellent soft magnetic characteristics by minimizing decrease in saturation magnetic flux density. <P>SOLUTION: A magnetic thin band of 60-600 μm thick composed of a magnetic material of alloy composition represented by a composition formula: Fe<SB POS="POST">a</SB>B<SB POS="POST">b</SB>Si<SB POS="POST">c</SB>P<SB POS="POST">x</SB>C<SB POS="POST">y</SB>Cu<SB POS="POST">z</SB>, where 79≤a≤86 at%, 5≤b≤13 at%, 0≤c≤8 at%, 1≤x≤8 at%, 0≤y≤5 at%, 0.4≤z≤1.4 at%, and 0.08≤z/x≤0.80, and an insulation layer of 5 μm thick or less are laminated alternately to form a laminate core. Space factor of the magnetic material in the laminate core is 85% or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
