Abstract: It is shown that for the transpose map $ \theta (n)$ of the $ n \times n$ matrix algebra $ {M_n}$, its $ k$ th multiplicity map $ \theta {(n)_k}$ has exactly the norm $ k$ if $ k \leqslant n$, hence the completely bounded norm of $ \theta (n)$ written $ {\left\Vert {\theta (n)} \right\Vert _{cb}}$ equals $ n$. Some applications and related results are also proved.
