Summary:To provide a method for producing a polyolefin resin foamed particle having excellent productivity and production cost.SOLUTION: A method for producing polyolefin resin foamed particles includes the steps of: mixing polyolefin resin particles, a dispersion medium, a silicate, a compound having a specific number of amino groups, and an inorganic foaming agent in a container, to prepare a dispersion; and releasing the dispersion to a zone of lower pressure than the container internal pressure.SELECTED DRAWING: None 【課題】生産性および生産コストに優れる、ポリオレフィン系樹脂発泡粒子の製造方法を提供すること。【解決手段】容器内でポリオレフィン系樹脂粒子、分散媒、ケイ酸塩、特定量のアミノ基を有する化合物、および無機系発泡剤を混合し、分散液を調製する工程と、分散液を容器内圧よりも低い圧力域に放出する工程とを有する、ポリオレフィン系樹脂発泡粒子の製造方法とする。【選択図】なし
