1. A translation enhancer used in a cell-free protein synthesis system, the translation enhancer consisting of a nucleic acid as a 3′ untranslated region linked adjacent to a 3′ terminus of a code region that encodes an amino acid sequence of a target protein,
wherein the 3′ untranslated region consists of:
a first region consisting of a sequence of 10 to 40 nucleic acids adjacent to the 3′ terminus of the code region, and
a second region consisting of a poly-A sequence having continuous 2 to 20 “A”s directly linked to the first region, and
wherein the first region has a hairpin structure,
the 3′ terminus of the first region is not “A”, and
no additional nucleic acid is linked to the 3′ terminus of the second region.
