1. A capillary electrophoresis device comprising:
a plurality of capillaries into which a sample to be measured is configured to be introduced and electrically separated;
a light source that generates light for analyzing the sample electrically separated by the plurality of capillaries;
a detector that detects light transmitted through the capillaries;
an optical coupling optical system and a plurality of first optical fibers provided between the light source and the plurality of capillaries; and
a plurality of second optical fibers provided between the plurality of capillaries and the detector,
wherein the optical coupling optical system couples the light from the light source to the plurality of first optical fibers,
wherein each of the plurality of first optical fibers has a first end face connected to the optical coupling optical system, and a second end face arranged close to and opposite to a corresponding capillary among the capillaries,
wherein each of the plurality of second optical fibers has a first end face arranged close to and opposite to a corresponding capillary among the capillaries, and a second end face connected to the detector,
wherein the optical coupling optical system includes an imaging optical system and a third optical fiber, and
wherein the third optical fiber has a first end face arranged at an image formation position of a light emitting surface of the light source formed by the imaging optical system, and a second end face directly connected to the plurality of first optical fibers.
