    摘要： The present invention relates to thermoplastic olefin elastomer expanded beads, having an average aspect ratio of 1.10 or less and an average circularity of 0.985 or more. The thermoplastic olefin elastomer expanded beads preferably have a crystal structure such that a melting peak inherent in the thermoplastic olefin elastomer (inherent peak) and one or more melting peaks on a higher temperature side than the inherent peak (high temperature peaks) appear on a DSC curve obtained when heating the expanded beads from 23° C. to 200° C. at a heating rate of 10° C./min.

    摘要： An object of the present invention is to provide expanded beads capable of producing an expanded beads molded article that is excellent in in-mold moldability and is excellent with good balance in lightweight property, flexibility, repulsion, restorability, and tensile characteristics, and an expanded beads molded article using the expanded beads. The expanded beads molded article of the present invention is produced by subjecting the crosslinked expanded beads of the present invention, to in-mold molding. The expanded beads molded article of the present invention may have an apparent density of from 40 to 150 g/L.
