A thin film element is a biomolecule, the biomolecule detection method, and a biomolecule detectio

PROBLEM TO BE SOLVED : To provide a thin film biomolecule detection element, a biomolecule detection method and a biomolecule detection device capable of precisely detecting biomolecules.SOLUTION : A thin film biomolecule detection element 7 has a substrate 2, a substrate suction section 1, a linker 6 and a rare earth complex 4. The substrate suction section 1 is disposed on the substrate. The linker 6 is adhered to the substrate suction section 1 via one end. The rare earth complex 4 is coupled with the other end of the linker 6.
