PURPOSE:To enhance insulating property by forming an insulating layer comprising at least one kind of element out of aluminum silicate, lithium silicate and magnesium methylate. CONSTITUTION:A nano-crystalline alloy thin band is represented by a formula of (Fe1-aMa)100-x-y-z-bAxM'yM''zXb(atm%) where M: at least one kind out of Co, Mi; A: at least one kind out of Cu, Au; M': at least one kind out of Ti, V, Zr, Nb, Mo, Hf, Ta, and W; M'': at least one kind out of Cr, Mn, Al, Sn, Zn, Ag, In, platinum group elements, Mg, Ca, Sr, Y rare earth elements, N, O, and S; X: at least one kind out of B, Si, C, Ge, Ga and P, in a nano- crystalline alloy thin band in the composition satisfying the following inequalities of 0<=a<=0.5, 0<=x<=10, 0.1<=y<=20, 0<=z<=20, 2<=b<=30, while at least one surface at the thin band is coated with a solution comprising at least one kind out of aluminum silicate, lithium silicate and magnesium silicate so as to form a dried and set insulating layer in the mean thickness not exceeding 2mum. |
