Abstract
Provided are poly(3-hydroxyalkanoate) foam particles, which can give a foam molded article having good surface aspects and a low shrinkage ratio of a molding, and the foam molded article. The poly(3-hydroxyalkanoate) foam particles have at least two melting peaks on a DSC curve obtained by differential scanning calorimetry and in which a melting calorie (X) on a high temperature side is 0.1 to 20 J/g, a gel fraction (Y) is 20 to 75% by weight, and the melting calorie (X) and the gel fraction (Y) satisfy Formula: X+Y≥30.
