Abstract: The k-partite entanglement, which focus on at most how many particles in the global system are entangled but separable from other particles, is complementary to the k-entanglement that reflects how many splitted subsystems are entangled under partitions of the systems in characterizing multipartite entanglement. Very recently, the theory of the complete k-entanglement measure has been established in [Phys. Rev. A 110, 012405 (2024)]. Here we investigate whether we can define the complete measure of the k-partite entanglement. Consequently, with the same spirit as that of the complete k-entanglement measure, we present the axiomatic conditions that a complete k-partite entanglement measure should require. Furthermore, we present two classes of k-partite entanglement and discuss the completeness of them as illustrations.
