The present invention provides a polysaccharide/functional compound complex comprising a functional compound and a multi-branched polysaccharide derivative, wherein the multi-branched polysaccharide derivative has a skeleton of a multi-branched polysaccharide composed of a saccharide as a structural unit, and at least one of the hydroxyl groups (OH) of the multi-branched polysaccharide is substituted by OR, wherein R represents a hydrogen atom, a hydrocarbon having 1 to 30 carbon atoms, or a hydrocarbon having 1 to 30 carbon atoms and hetero atom. The functional compound can be efficiently incorporated into polysaccharide derivative, and further by exposing the polysaccharide complex to an environment such as a solution, sustained release of the functional compound can be controlled. By utilizing this property, the complex can be efficiently used in external preparations for skin such as cosmetic products.
