An embodiment of the present invention is to provide a bioabsorbable medical material having adhesiveness to a biological tissue and improved degradability. A bioabsorbable medical material according to an embodiment of the present invention contains a crosslinked polymer material forming a specific shape, and a disintegration delaying material retained by the crosslinked polymer material. The crosslinked polymer material has degradability in water, the degradability being suppressed in the presence of an acid. The disintegration delaying material releases 0.5 mol%/day or greater of an acid until the seventh day upon contact with water at 37°C.
