In this article, we construct the scalar-diquark–scalar-diquark–antiquark type current to study the ground state triply-charmed pentaquark states with the QCD sum rules. We separate the contributions of the negative-parity and positive-parity triply-charmed pentaquark states explicitly, and take the energy scale formula to determine the optimal energy scales of the QCD spectral densities. The predicted pentaquark masses can be confronted to the experimental data in the future.
