12 Claims

1. An ester-based elastomer expanded molded article comprising a fusion of expanded particles that contain an ester-based elastomer as a base resin,

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.
