    In this talk, I will present a recent progress of the investigation of the QCD phase structure by using the imaginary chemical potential and effective models of QCD. At finite imaginary chemical potential, QCD has several characteristic properties such as the Roberge-Weiss periodicity and transition. These properties are quite important to construct and/or extend the effective model. Moreover, the imaginary chemical potential can be converted to the temporal fermion boundary condition and thus its knowledge may be useful when we investigate the Hosotani mechanism in QCD-like gauge theory where the fermion boundary condition plays a crucial role.
