摘要： A substrate for mass spectrometry includes a first reflective member that is semi-transmissive/semi-reflective, a transparent member, and a second reflective member that is reflective, sequentially provided to form an optical resonator. The optical resonator includes, on a surface of the first reflective member, a sample separation portion at which surface interaction occurs with a plurality of analytes contained in a sample liquid. The analytes are separated on the sample separation portion to perform mass spectrometry on each of the analytes. A sample in contact with the surface of the first reflective member is irradiated with laser beam L to generate resonance in the optical resonator, and an electric field on the surface of the first reflective member is enhanced by the resonance. The enhanced electric field is utilized to ionize analytes S in the sample and to desorb the analytes S from the surface.
