Provided is a non-tubular brain damage recovery material which is used to cover and/or fill a damaged part of the brain, the brain damage recovery material including: (A) a cross-linked body with which a bioabsorbable polysaccharide having a carboxyl group in a low endotoxin molecule is covalently bonded and cross-linked with at least one crosslinking reagent selected from among a compound represented by general formula (I) and salts thereof； and (B) a bioabsorbable polymer. R1HN—；(CH2)n—；NHR2 (I) [in the formula, R1 and R2 each independently represent a hydrogen atom or a group represented by formula of —；COCH(NH2)—；CH2]4—；NH2, and n represents an integer from 2 to 18]. Accordingly, provided is a medical material which can recover a damaged part of the brain.
