OPTICAL ANALYZING UNIT AND OPTICAL ANALYZING DEVICE

摘要

Light emitting elements (47) and light receiving elements (49) are respectively disposed at the relative opposite ends of a waveguide unit (43) having a plurality of cores (51) so as to face the end faces of relative cores (51). A switching unit (44) is overlapped on the waveguide unit (43). Switching windows (52) are arranged cross-wise on the switching unit (44) so as to allow lights propagating through the cores (51) to be switched between a light transmitting state and a light reflecting state, with a plurality of switching windows (52) arranged along the upper surface of each core (51). An inspection substrate (45) having a plurality of flow paths (60) each formed with a metal thin film (61) is disposed on the switching unit (44), and a receptor (62) is fixed on each film (61) in each flow path (60). A material under inspection containing a specific ligand is allowed to flow through each flow path (60).
