An electro-magnetic wave shield cover having an array of first yarn members () formed by bundling () ends of polyester fibers around which a tin-plated copper metallic foil () is wound. The second yarn member () is formed by bundlingends of polyester fibers. Doubled-yarn groups (A,B,C,D) of the first yarn members running in the first direction (warp) from upper right to lower left and doubled-yarn groups (A,B,C,D) of the second yarn members () running in the first direction (warp), and doubled-yarn groups () of the first yarn members running in the second direction (weft) from upper left to lower right and doubled-yarn groups () of the second yarn members running in the second (weft) direction are arranged so that the interlacing is made in such a manner that if the doubled-yarn group, running in the one direction is twice disposed beneath the doubled-yarn groups running in the other direction, then it is twice disposed above the latter.
