The reusable SERS molecular test device includes two glass sheets, wherein a noble metal nano film is deposited on the surface of one of the glass sheets to form an SERS substrate, a metal ring is formed by depositing on an edge region of the SERS substrate by means of a coating process, and the metal ring fits with the SERS substrate to form a two-dimensional air chamber; and the other glass sheet, on which molecules under test are adsorbed and immobilized, is placed upside down on the metal ring, the thickness of the layer of the molecules under test being not greater than the thickness of the metal ring. The SERS molecular test device can fundamentally prevent the SERS substrate from being irreversibly contaminated by the molecules under test, so that the SERS substrate can be used in a cleaning-free and reusable manner.
