In this paper, we have studied first the idea of rough continuity of real valued functions of real variables and then we have discussed some important properties of rough continuity. Then we study the idea of rough $\mathcal{I}$-continuity of real valued functions and find the relation between rough $\mathcal{I}$-continuity and rough continuity. We also introduce the notion of rough $(\mathcal{I}_1, \mathcal{I}_2)$-continuity and rough $\mathcal{I^*}$-continuity of real valued functions and discuss some properties on these two types on continuity.
