PROBLEM TO BE SOLVED: To provide an antibody that binds to a programmed death ligand 1 (PD-L1) protein of a T cell co-inhibitory factor ligand, and a method for using the same. An isolated antibody or antigen-binding fragment thereof that binds to human programmed death ligand 1 (PD-L1) protein, the three complements of a heavy chain variable region (HCVR) having a specific amino acid sequence. Includes sex determining regions (CDRs) (HCDR1, HCDR2, and HCDR3) and three complementarity determining regions (CDRs) (LCDR1, LCDR2, and LCDR3) of the light chain variable region (LCVR) having a specific amino acid sequence , An isolated antibody or an antigen-binding fragment thereof.
