It is shown that the complex scaling method is very useful in not only calculating the resonance energies and widths but also studying the structure of continuum states of many-body systems. Using the extended completeness relation consisting of bound, resonant and continuum solutions for the complex-scaled Hamiltonian, the strength function of a transition operator is expressed in the corresponding three terms. This method is applied to the electromagnetic dissociation reaction of 6He which is described by a 4He+n+n three-body model. The dipole transition strength distribution in the continuum states is discussed to have a low-energy enhancement coming dominantly from the break-up transition to 5He(3/2)+n.
