We point out that the complex scaling method is one of the most successful framework to study many-body resonances. As recent developments of the complex scaling method, we present several ways to analyze the properties of resonant states; the matrix elements associated with resonant states, the extended completeness relation and partial widths of resonances. We also discuss the binding mechanism and excited resonant structure of the Borromean systems: 4He+n+n and 9Li+n+n. We show that the pairing correlation between valence neutrons and between core neutrons plays an important role in neutron-rich nuclei.
