Coherence measures induced by norm functions are studied. It is shown that a coherence measure cannot be induced by a unitary similarity invariant norm. As a consequence, one can deduce the known fact that the Schatten $p$-norms do not induce coherence measures. For $(p,q) \in [1,\infty]\times [1,\infty]$, the $\ell_{q,p}$-norm of a matrix with columns $A_1, \dots, A_n$ is defined as the $\ell_q$-norm of the vector $(\ell_p(A_1), \dots, \ell_p(A_n))$. It is shown that the $\ell_{q,p}$-norm induces a coherence measure if and only if $q = 1$ and $p \in [1,2]$. This result gives rise to a new class of coherence measures, and explains why the $\ell_p$-norm, corresponding to the $\ell_{p,p}$-norm, induces a coherence measure if and only if $p = 1$.
