The invention discloses an anti-uPAR (urokinase plasminogen activator receptor)-antigen humanized antibody H2DL2 and an application thereof. An IgG named antibody H2DL2 is provided firstly, CDR1, CDR2 and CDR3 in a heavy chain variable region of the IgG are shown sequentially as 50th-54th-position amino acid residues, 69th-85th-position amino acid residues and 118th-126th-position amino acid residues from the N terminal in the sequence 1 of the sequence table, and CDR1, CDR2 and CDR3 in a light chain variable region of the IgG are shown sequentially as 45th-54th-position amino acid residues, 70th-76th-position amino acid residues and 109th-116th-position amino acid residues from the N terminal in the sequence 3 of the sequence table. The provided antibody H2DL2 has good binding activity with human uPAR protein, can remarkably inhibit tumor cell migration and has broad application prospect in the field of tumor treatment.
