ABSTRACT:
At both ends of a waveguide43having a plurality of cores51, light emitting elements47and light receiving elements49are disposed so as to face end faces of the cores51. A switch44is overlapped over the waveguide43. In the switch44, switching windows52each can be switched between a state where light propagating through the core51is passed and a state where the light is reflected are arranged in the vertical and horizontal directions, and the switching windows52are arranged along the top faces of the cores51. A test board45having a plurality of channels60in each of which a metallic thin film61is formed is disposed over the switch44, and receptors62are fixed on the metallic thin film61in the channels60. A specimen containing a specific ligand is passed in each of the channels60.
