A biomolecule analysis method of the present disclosure includes: preparing a biomolecule analysis device that includes a thin film having a nanopore with a diameter in a range of ±20% of a diameter of a biomolecule, a first liquid tank and a second liquid tank separated by the thin film, a first electrode disposed in the first liquid tank, a second electrode disposed in the second liquid tank, and a biopolymer degradation mechanism that degrades a biopolymer into the biomolecule; degrading a biopolymer into the biomolecule in the biopolymer degradation mechanism; and applying a voltage between the first electrode and the second electrode in a state where a measurement solution is enclosed in the first liquid tank and the second liquid tank, and measuring a current flowing between the first electrode and the second electrode, in which the measurement solution contains ammonium ions and sulfate ions.
