Disclosed is a molecular library comprising a group of a plurality of molecules, wherein each member of the library is a polypeptide having a randomized sequence moiety and a microprotein moiety. The microprotein is a protein comprising an amino acid sequence of 30 or less amino acid residues having the ability to form a particular conformation by spontaneous folding in a solution and is, for example, chignolin comprising the amino acid sequence represented by SEQ ID NO: 1. Also, disclosed is a method for identifying a novel functional molecule using the library of the present invention.
