SAMPLE HOLDING CARRIER, AND FLUORESCENCE DETECTION SYSTEM AND FLUORESCENCE DETECTION DEVICE THAT USE SAME

摘要

The present invention provides a sample holding carrier that can accurately measure a sample with a simple configuration, and a fluorescence detection system and a fluorescence detection device that use the same. Biosensor substrate (10) includes: base substrate (11) on which excitation light is incident from a lower surface; reflecting film (14) that is arranged on an upper surface of base substrate (11) to partially reflect the excitation light; and plural wells (13) that are arranged on an upper surface side of reflecting film (14) and have bottom surface portions (13a). The excitation light is converged to be incident on base substrate (11). Distance d3 from reflecting surface (11a) that is of a boundary between reflecting film (14) and base substrate (11) to bottom surface portion (13a) of well (13) is less than or equal to a focal depth of the excitation light. Therefore, the sample accommodated in bottom surface portion (13a) of well (13) can surely and efficiently be irradiated with the excitation light, and accurately be measured.
