A peculiar phenomenon in evaporation and condensation problems would be the existence of the so-called negative mass flow in the sense that the direction of the mass flows may become opposite to what one would usually expect to be. This phenomenon was first noticed by Sone and Onishi but has long been left untouched since then. Recently, the detailed study on this phenomenon has been carried out by Onishi. However, the fact that the thermal conductivity of the condensed phase is finite is not taken into account, in spite of the well-known fact that the finite thermal conductivity of the condensed phase may change drastically the role of the latent heat parameter and, hence, the mass and energy flows, leading to the existence of their maximum values. It is the present study to clarify its effects on the existence and the magnitude of this negative mass flow by taking up a simple two-surface problem of evaporation and condensation.
