PURPOSE: To suppress leakage of electromagnetic wave by using a magnetic body of each row for the surround of a contact part and a door of a metal enclosure by dividing it into two or more parts while sandwiching a plate-shaped conductor in longer direction in a section which is vertical to a contact surface with the conductor.
CONSTITUTION: An electromagnetic shielding body 1 is in one-piece structure by combining a conductor 2 whose section is in rectangular shape and a magnetic body 3 in rectangular shape in a row alternately. The magnetic body 2 in each row is divided into a plurality of parts by a conductor plate 5 in the section. The conductor 2 and the conductor plate 5 are constituted of a macromolecular material, etc., which is subjected to conductive treatment such as metal plating and conductive filler mixing. The magnetic body 3 is constituted of a sintered ferrite material, a macromolecular material where ferrite powder is mixed, or a magnetic alloy. By applying the magnetic shielding body 1 to a seam, a spacing, etc., of the metal enclosure, leaked electromagnetic wave can be suppressed while non-contact or contact is not reinforced.
