Abstract
The present invention provides a powder which is capable of forming a tissue covering material that is capable of exhibiting a further function while having high adhesive strength to living tissues. The powder includes first particles that each contain a crosslinked gelatin derivative, and second particles that are different from the first particles and can provide a further function. The gelatin derivative has a structure represented by formula (1). In formula (1), Gltn represents a residue of gelatin, L represents a single bond or a divalent linking group, R1 represents a hydrocarbon group having 1 to 20 carbon atoms, and R2 represents a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms.
