発明の名称 (英語) COMPOSITE MATERIAL
発明の概要(英語) The purpose of the present invention is to provide a composite material which can easily be recovered from inside a living organism. The problem addressed by the present invention is solved by a composite material obtained by joining a substrate and a temperature-responsive porous body to one another, and characterized by containing heat-generating particles. The present invention makes it possible to easily recover the composite material from the implantation site.
