<P>PROBLEM TO BE SOLVED: To provide an foaming molded body which has excellent fatigue resistance to repeated compression. <P>SOLUTION: Regarding the foaming molded body, bubbles are dispersed into a base material resin. The bubbles are formed in such a manner that a thermally expandable microcapsule in which a volatile liquid as a core agent is involved in a shell including a polymer is thermally expanded. The average adhesion index between the shell of the thermally expandable microcapsule after the thermal expansion and the base material resin is ≥7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
