摘要：Composite resin particles comprising 50 to 800 parts by mass of a polystyrene-based resin with respect to 100 parts by mass of a polyolefin-based resin, wherein: whentransmission electron microscope (TEM) images obtained by photographing cross-sections of the composite resin particles using a TEM at a magnification of 1,000 aresubjected to a binarization processing and areas in the obtained binarized images whichcorrespond to a cross-sectional area of 437.584 µm of the composite resin particles aresubjected to image analysis, the polystyrene-based resin satisfies the followingrequirements: (1) the number of dispersed particles is 180 or more; (2) the maximum ofthe areas of dispersed particles is 200 µm or less; and (3) the coefficient of variation indispersion is 100% or more, and the composite resin particles exhibit an inner

morphology that includes a mixture of sea-island structure regions in which particles ofthe polystyrene-based resin are dispersed in the polyolefin-based resin and co-continuous structure regions in which particles of the polystyrene-based resin having anindefinite shape is dispersed in the polyolefin-based resin.
