• Every nonzero integral ideal can be expressed as the product of finite prime ideals in Dedekind domain. For each integral ideal $\mathfrak{A}$, it is essential to measure the multiplicity of its prime ideal factors. We define $\lambda(\mathfrak{A}): = \frac{\log N(\mathfrak{A})}{\log \gamma(\mathfrak{A})}$ to be the index of composition of $\mathfrak{A}$, where $\gamma(\mathfrak{A}) = \prod_{\mathfrak{P}|\mathfrak{A}}N(\mathfrak{P})$ and $N(\mathfrak{A})$ is the norm of ideal $\mathfrak{A}$. In this paper, we obtain an $\Omega$-result for the mean value of the index of composition of integral ideal.
