    摘要： A process for producing polylactic acid-based resin expanded beads by releasing foamable resin particles, which are in a softened state and dispersed in a dispersing medium contained in a pressure resisting closed vessel, to an atmosphere having a pressure lower than that in the closed vessel together with the dispersing medium to foam and expand the foamable particles. The foamable resin particles are obtained by impregnating a physical blowing agent into resin particles which are formed of a modified polylactic acid resin modified with an epoxide and showing specific physical properties when melted.
