Abstract. Given a positive odd integer $p$ with $p\geq 3,$ the Cantor $p-$ary $C_p$ set and the Cantor $p-$ary function $f_p$ are constructed. $C_p$ is a generalization of the Cantor set in the case that the measure of the set $C_p$ is still zero and $f^{\infty}_p$ defined on the Hilbert Cube $Q$ is a generalization of the Cantor function. Also, for any $s\in (0, 1),$ let

\begin{displaymath}G^s_{f^{\infty}_{p}}=\{\{s\}\times \Big(f^{\infty}_{p}\Big)^{-1}(c)~\vert~ c\in Q_2\}\end{displaymath}

and $S$ is the set of all singletons in $\Big([0, s)\cup (s, 1]\Big)\times Q_2.$ Then $G=G^s_{f^{\infty}_{p}}\cup S$ is an upper semi continuous decomposition on the Hilbert Cube $Q.$ Moreover, $Q/G$ is homeomorphic to $Q.$
