Satoh and Taniguchi define a numerical invariant called an n-writhe. This invariant induces a lot of virtual knot invariants such as an index polynomial, an odd writhe polynomial and an affine index polynomial. In this talk, we show that there exists infinitely many virtual knots whose n-writhes are all zero.
