Summary: | PROBLEM TO BE SOLVED: To provide a safe and stably suppliable biodegradable material obtained by improving hard and brittle properties which are problems of a polylactic acid, and to provide a material for medical application such as a footing material for tissue regeneration including the biodegradable material. SOLUTION: The branched biodegradable polyester has a polyglycerol as a main chain, and polyester chains as side chains through the hydroxy groups of the polyglycerol. Concretely, the branched biodegradable polyester is represented by general formula (A) (wherein, R is independently a hydrogen atom or a polyester chain, with the proviso that 50% or more of the R is the polyester chain; and n is 2-20).
