PROBLEM TO BE SOLVED: To provide a method for dyeing a cellulosic fiber structure without modifying the cellulosic fiber by using supercritical carbon dioxide as a medium by which the cellulosic fiber structure is dyed uniformly into a deep color with a high fastness while loading a small environmental load. SOLUTION: When dyeing the structure including a cellulosic fiber dyeable with disperse dye by using the supercritical carbon dioxide as the medium, a lower alcohol is added to the medium. The cellulosic fiber dyeable with disperse dye contains 1-40wt.% polymer particles of a compound having an aromatic ring, and a carbon atom neighboring the aromatic ring and having at least one of an ester bond and an ether bond.
