Abstract In this paper, the notion of $C-$spectral norm is introduced for operators; it was defined and studied for matrices before. Here, some $C-$spectral norm inequalities between operator matrices and their operator entries, for $2\times 2$ and $n \times n$ operator matrices, are studied. Also, some $C-$spectral norm equalities between operator matrices are brought.
