Nerve regeneration-inducing material

A non-tubular material for nerve regeneration induction use, which can be used for the regeneration of a damaged part in a nerve, and which comprises: (A) a crosslinked substance produced by crosslinking a low-endotoxin bioabsorbable polysaccharide having a carboxyl group in the molecule with at least one crosslinkable reagent selected from a compound represented by general formula (I) and a salt thereof via covalent bonds; and (B) a bioabsorbable polymer. R 1 HN-(CH 2 ) n -NHR 2 (I) [wherein R 1 and R 2 independently represent a hydrogen atom or a group represented by formula: -COCH(NH 2 )-(CH 2 ) 4 -NH 2 , and n represents an integer of 2 to 18] Thus, a medical material that can induce the regeneration of a damaged part in a nerve is provided.
