Abstract: A bulk-density measuring device includes a first vessel in which contracted pre-expanded particles are swollen and recovered from contraction in a pressure-reduced state where a vessel internal pressure is lower than atmospheric pressure; a second vessel filled with the pre-expanded particles after being swollen in the first vessel in the pressure-reduced state where a vessel internal pressure is lower than the atmospheric pressure, and into which the pre-expanded particles of a constant volume are collected fractionally; a pressure-reducing unit that adjusts the vessel internal pressures of the first vessel and the second vessel to be lower than the atmospheric pressure; and a scale that measures a weight of the pre-expanded particles filled in the second vessel.
