The object of the present invention is to provide a biodegradable bio-absorbable material for clinical practice having excellent degradation profiles, heat resistance and a mechanical property. The present invention provides a biodegradable bio-absorbable material for clinical practice, which comprises the following A-type polymer and B-type polymer: wherein X1 and X2 are in the range of 0 to 50 mole %, Y1 and Y2 are in the range of 0 to 50 mole %, Z1 and Z2 are in the range of 50 to 100 mole %, m1 and m2 are in the range of 3 to 8, R1 and R3 are the hydrogen or C1-4 alkyl group, R1' and R3' are the C1-2 alkyl group, and R2, R2', R4 and R4' are the C1-4 alkyl group provided that Y1 is 0 mole % when X1 is 0 mole %, Y2 is 0 mole % when X2 is 0 mole %, and X1 and X2 are not 0 mole % at the same time.
