摘要： Expanded beads are those including a mixture of an olefin-based thermoplastic elastomer and a polyethylene-based resin, wherein a melt flow rate MFR(I) of the olefin-based thermoplastic elastomer is 2-10 g/10 min; a difference ((MFR(II))−(MFR(I))) between a melt flow rate MFR(II) of the polyethylene-based resin and the melt flow rate MFR(I) of the olefin-based thermoplastic elastomer is 1-35 g/10 min; and a content of the polyethylene-based resin in the mixture is 3-40% by weight.
