 note = {We have performed the measurements of the vapor pressure and heat capacity for inert layer 4He adsorbed on a mesoporous silica. The heat capacity was found to exhibit a Schottky peak, indicating the excitation of the localized solid to fluid. We analyzed the heat capacity over a wide temperature range according to a model that considers the contribution of the localized solid and excited fluid, and clarified that the excited fluid coexists with the localized solid at high temperatures. Based on the areal density dependence of the amount of excited fluid, we discuss the formation of an inert layer prior to the appearance of a superfluid layer.},
