Abstract
An object of the present invention is to provide an aromatic polyester-based resin foam molded product having excellent mechanical properties, foamed aromatic polyester-based resin particles for producing the foam molded product, or a method for producing the foamed particles. The present invention relates to foamed aromatic polyester-based resin particles, wherein crystallinity (A) in a particle central portion and crystallinity (B) in a particle surface layer are both 10% or less, and a ratio of the crystallinity in the surface layer to the crystallinity in the central portion (B/A) is 0.3 to 1.4.
