An artificial antibody library with a super-repertory (10<SUP>11 </SUP>or more) is constructed by: using a cDNA library as a template, amplifying a fragment containing the CDR1 and CDR2s regions of the VH or VL region of immunoglobulin gene and a fragment containing the CDR3 region each by the PCR method; integrating the VH library and the VL library, which are little contaiminated with unexpressionable repertory and have high safety, into an nono-expression vector; transferring it into a host; and then shuffling the VH region in the VH library with the VL region in the VL library.
