To obtain a magnetic wave-insulating three-dimensional structural body having a large degree of freedom in designing and applicable to a complicated steric shape by using a metal-coated yarn or an electroconductive fiber yarn in at least a part of the yarns constituting a woven knitted fabric of a steric structure having continuous holes.
This magnetic wave-insulating three-dimensional structural body comprises a woven knitted fabric of a three dimensional steric structure having continuous holes shown bellow: a number of connection poles 4 consisting of yarns coated with metal coatings which are prepared by electroless plating and arranged with a specified space between themselves are placed between an upper layer 2 and a lower layer 3 consisting of constituting yarn of the metal coated yarn same as the above mentioned yarns; both the ends of the connection poles 4 are connected to both the upper layer 2 and the lower layer 3; many openings 2a and 3a formed on both the upper layer 2 and the lower layer 3 are connected to a number of spaces formed among the connection poles 4. Further, an electroconductive fiber yarn may be used in the place of the above metal-coated yarn.
