1. A fluorescence sensor comprising:
- a fluorescence unit that generates fluorescence in an amount correlating with concentration of analytes by receiving excitation light;
a measurement optical system that emits the excitation light and detects the fluorescence from the fluorescence unit;
a sensor body in which the measurement optical system is embedded;
a light guide unit that is optically connected to the sensor body and bi-directionally guides light between the measurement optical system and the fluorescence unit;
wherein the light guide unit includes at least an optical-waveguide film on which one or more optical waveguides are formed;
the optical-waveguide film includes a plurality of optical channels that output the excitation light or input the fluorescence; and
each of the plurality of optical channels is covered with the fluorescence unit.

Abstract
A light guide unit of a fluorescence sensor is disclosed, which includes at least an optical-waveguide film in which one or more optical waveguides are formed. Each of these films includes a plurality of optical channels that output excitation light (E) or input fluorescence (F). All the optical channels are covered with a fluorescence unit.
