Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a laser multigas analyzer which offers enhanced strength of a target gas absorption signal by having the emission side emit light beams from a plurality of laser beam sources of different wavelengths into a space without using fiber couplers, which eliminates insertion loss on the emission side and efficiently transmits optical power to a photosensor.SOLUTION: A laser multigas analyzer 1 comprises; a light emission section 100 which emits laser beams, for analyzing a plurality gases, from pigtail light-emitting elements 11a, 11b, 11c, 11d that have propagated through single mode optical fibers 12,a 12,b, 12c, 12d, respectively, which are bundled together at a fiber bundle end 21 to bring emission points close together; and a light reception section 200 for analyzing properties of the plurality of gases using a detected signal.
