The invention belongs to the field of antibody drug, and discloses a full human-derived anti-human VEGFR2 monoclonal antibody screened by a phage antibody base technology and prepared by a gene engineering method, and further discloses a carrier including polynucleotide for encoding the monoclonal antibody, a host cell and an application. Through combining with VEGFR2, the monoclonal antibody stops the combination of VEGF with VEGR2, and does not induce receptor dimerization, cause the following tyrosine residue phosphorylation in intracellular tyrosine kinase structure and activate downstream signal access including activation of phospholipase C and increase of calcium ion concentration in the cell and others; the antibody drug triggers endothelial proliferation, survival, cytoskeleton rearrangement, cell migration, gene expression and others, and finally stops the vascular proliferation caused by combination of VEGF and VEGFR2 and induction of dimerization. The monoclonal antibody can be used for treating diseases caused by tumor angiogenesis.
