Let $\Phi$ be a non-negative locally integrable function on ${\mathbb{R}}^n$ and satisfy some weak growth conditions, define the potential type operator $T_{\Phi}$ by $$T_{\Phi}f(x)=\int_{{\mathbb{R}}^n} \Phi(x-y)f(y)\d y.$$ The aim of this paper is to give several strong type and weak type weighted norm inequalities for the potential type operator $T_{\Phi}$.
