An electro-magnetic wave shield cover having an array of first yarn
members (10) formed by bundling (48) ends of polyester fibers around
which a tin-plated copper metallic foil (12) is wound. The second yarn
member (20) is formed by bundling 96 ends of polyester fibers.
Doubled-yarn groups (10A, 10B, 10C, 10D) of the first yarn members
running in the first direction (warp) from upper right to lower left and
doubled-yarn groups (20A, 20B, 20C, 20D) of the second yarn members (20)
running in the first direction (warp), and doubled-yarn groups (10a, 10b,
10c, 10d) of the first yarn members running in the second direction
(weft) from upper left to lower right and doubled-yarn groups (20a, 20b,
20c, 20d) 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.
