1. A magnetic-plate laminated body comprising:
- a laminated part made up of a plurality of laminated soft magnetic ribbons;
first and second metal plates that sandwich the laminated part from upper and lower surfaces in a lamination direction of the laminated part; and
a fastening mechanism that penetrates the first and second metal plates and the laminated part and fastens the laminated part to the first and second metal plates,wherein the soft magnetic ribbons have surfaces with wrinkles such that adjacent pairs of the soft magnetic ribbons locally contact each other and have clearances between the wrinkles where the soft magnetic ribbons contact each other.
