The first strands 8 are flat strands. The second layer 6 is formed by twisting together eight second strands 10. The second strands 10 are flat strands. In each of the strands, the ratio (Ww/Tw) of the width Ww of the strand to the thickness Tw of the strand is in the range of 2 to 11, inclusive. The twisting direction of the second strands 10 is opposite that of the first strands 8. The twisting angle of the first strands 8 is 85º or less.
