PROBLEM TO BE SOLVED: To efficiently show the shielding effect of an electromagnetic wave by overlapping at least two knitting fabrics made of conductive fiber while a stitch is shifted. SOLUTION: At least two knitting fabrics are overlapped while a stitch is shifted. More specifically, the knitting fabrics are shifted up and down, and are preferably overlapped so that courses cross orthogonally. For three types, namely 'parallel/parallel', 'parallel/cross', and 'cross', a result where a magnetic field shield ratio is measured by the KEC method is showen in a figure. As shown in the figure, in the case of 'parallel/cross', shield efficiency is excellent. On the other hand, in the case of 'cross', the shield efficiency is nearly the same or slightly lower than the case of 'parallel/parallel'. Therefore, when the woven texture is created by the minimum amount of conductive fiber according to a target, electronic waves can be shielded effectively with this kind of configuration.
