PURPOSE: To obtain an anechoic enclosure of high performance and good construction workability by preventing wave absorption performance from lowering due to generation of a magnetic clearance between a ferrite board applied to an electromagnetic shield panel in advance and a ferrite board to be applied to a joint part.
CONSTITUTION: An anechoic enclosure is provided with a junction structure of a ferrite board wherein a plurality of electromagnetic wave shield panels 10 wherein ferrite boards 13, 14 are applied to a region excepting a shield connecting part 30 are connected mutually by a shield connection part 30 and a ferrite board 16 covering the shield connection part 30 and a side edge part of the ferrite board 14 on an electromagnetic wave shield panel adjoining thereto are joined mutually by a shiplap structure.
