A fluorescent light detection device includes: an excitation light source; an excitation light fiber; a fluorescent light fiber; a detector configured to receive the fluorescent light emitted from the fluorescent light fiber; a retention member configured to retain the fibers so that an emitting end face of the excitation light fiber and an incident end face of the fluorescent light fiber are located at close proximity; an excitation light selection filter provided in contact with the emitting end face; and a fluorescent light selection filter provided in contact with the incident end face. The excitation light emitted from the emitting end face irradiates a test object via the excitation light selection filter and the fluorescent light produced by the test object is incident on the incident end face via the fluorescent light selection filter.
