A polysaccharide derivative has a partial structure represented by Formula (1) below. It is preferable that at least one of the amino acids that constitute Xin Formula (1) below is a basic amino acid. 

Polysaccharide derivative having membrane-permeable peptide chain

A polymer compound has a group represented by Formula (1) or Formula (2) in a side chain. (In Formula (1), Xrepresents a neutral amino acid residue or an &#x3c9;-aminoalkanoic acid residue, Xrepresents a membrane-permeable peptide residue, Xrepresents a hydroxyl group, an amino group, an alkoxyl group having 1 to 4 carbon atoms, or a benzyloxy group, and a represents a number of from 1 to 50.) (In Formula (2), Xrepresents a neutral amino acid residue or an &#x3c9;-aminoalkanoic acid residue, Xrepresents a membrane-permeable peptide residue, Xrepresents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a benzyl group, an acyl group having 1 to 6 carbon atoms, an arylsulfonyl group, or a carboxyl group, and b represents a number of from 1 to 50.).
