Abstract: A spectroscopic analysis apparatus includes a laser light source that emits laser light, of which wavelength changes, toward a reflector inside a probe, the probe being configured to be disposed in a flow passage of a measurement target fluid, a light receiver that receives the laser light reflected by the reflector, and a controller that analyzes the measurement target fluid using a result of reception acquired by the light receiver and controlling the laser light source. The controller controls the laser light source to perform at least one scan of the laser light, the controller controlling the laser light source such that a scanning time of the laser light is equal to or shorter than a light-receivable time of the laser, the scanning time being a time to scan the laser light emitted from the laser light source in a certain wavelength range, the light-receivable time being a time in which the laser light reflected by the reflector can be received by the light receiver.
