    Abstract: PURPOSE: A manufacturing method of a biodegradable microsphere is provided to obtain micro particles having structural complexity inside and outside at the same time through simple method on the basis of biodegradable polymers using for medical treatment. CONSTITUTION: A manufacturing method of a biodegradable microsphere comprises a step of manufacturing polymer solution containing biodegradable polymers and phase change material, and a step of solidifying the biodegradable microsphere by manufacturing emulsion oil-in-water through dispersing the polymer solution into continuous phase in which hydrophilic surfactant is dissolved. The biodegradable polymer is poly(D,L-lactic acid) or poly(lactic acid-co-glycolic acid). The biodegradable polymer is added to have the concentration to organic solvent in the polymer solution of 6-10 %(w/w).
