Abstract

A sewn product comprises fabrics having conductive yarns inserted each in a warp direction and a weft direction and disposed in a lattice at intervals, wherein at least two stitches in at least one place of seam are provided with a stitch interval of not more than 5 mm, and a surface resistance (R) between two points separated by 30 cm across at least one seam is according to the formula: R≦1.0×10¹²Ω. A sewn product comprises fabrics having conductive yarns inserted each in a warp direction and a weft direction and disposed in a lattice at intervals, wherein in at least one place of seam a number of piles of clothing fabrics of seam allowance is 5 or more, and a surface resistance (R) between two points separated by 30 cm across at least one seam is R≦1.0×10¹²Ω.
