Abstract： A rigorous spectral representation of relativistic random-phase approximation is presented. Explicit expression is derived for the effective particle-hole interaction which contains the direct term Kan, the exchange term Ksc and the kernel for the fermion line renormalization Kfr. It is shown that according to our method, not only Kanan but also Ksc and Kfr can be given rigorously in a form which depends only on one ω(energy)-variable and they all take account of the retardation effect properly.
