The present invention relates to a novel antibody library and an antibody-screening method using same. Having a human sequence-derived specific VH or VL scaffold, the antibody library according to the present invention exhibits high thermodynamic stability and enjoys the advantages of allowing high soluble expression as well as reversible folding. In addition, the antibody according to the present invention includes a variety of rationally controlled CDRs so as to exhibit high specificity and high affinity to all antigens and thus can be advantageously used for selecting an adequate candidate antibody against a target antigen.
