Molded foam of ester-based elastomer, uses thereof, and expanded beads of ester-based elastomer

Ester-based elastomer expanded particles comprising an ester-based elastomer as a base resin and capable of providing an expanded molded article that comprises a fusion of expanded particles,

• wherein the ester-based elastomer contains a hard segment and a soft segment,
• wherein the hard segment is formed with
• a dicarboxylic acid component, and
• a dicarboxylic acid component and a diol component, and
• wherein the soft segment is an aliphatic polyether and/or polyester,
• wherein the ester-based elastomer contains the hard segment at 30 to 55% by mass, and
• wherein the dicarboxylic acid component is constituted of only terephthalic acid, or contains a terephthalic acid component and a dicarboxylic acid component other than the terephthalic acid component, the content of the dicarboxylic acid component other than the terephthalic acid component being less than 5% by mass.
