PURPOSE:To improve the yield while decreasing the process by forming a sheet having plural shields and spacers through the blanking of a strip thin plate so as to obtain the laminate shield ban with heat treatment, lamination and cutting at each sheet. CONSTITUTION:After the strip thin plate 8a is blanked by a sequential feeding press machine, the result is fed to a cut press and cut off into sheets 18 of a prescribed length with respect to the position of a pilot hole 10. A shield ban 2(11), a spacer 3 and a partition ban 4 are formed as the sheet 18 by the similar process. The shield ban 11 obtained in this way is heat-treated and magnetic annealing is applied. Then a resin is applied to each sheet 18 of the shield ban 2(11), the spacer 3 and the partition ban 4, a jig is used, they are laminated in a predetermined order with respect to the pilot hole 10, after they are released from the jig, the result is separated from coupled parts 12, 14, 15 to obtain a complete laminate shield ban 1.
