From the emission line spectra of active prominences observed by the solar telescope of the Kwasan Observatory, we investigated the asymmetry of Hα, Hβ, H and K line profiles by drawing their central lines. From this investigation the followings are concluded: (1) Almost all of active prominences show asymmetric profiles in these lines. (2) The sign of asymmetry is of the same in Hα　and Hβ, but the amount of asymmetry is much greater in Hα than in Hβ. (3) The H and K lines show the opposite sign of asymmetry to that in Hα and Hβ　and the amount of asymmetry is of the same order in the H and K lines.
