Zusammenfassung:	A multiple-reflection apparatus and a multiple-reflection cell includes: a pair of parallel plane mirrors that multiply reflects a laser light, in zigzag, which enters at a specific angle of incidence; a right-angle double mirror having two perpendicular reflection surfaces for returning the multiple-reflection light that traveled to one end between the parallel plane mirrors; and a right-angle double mirror having two perpendicular reflection surfaces for returning the multiple-reflection light that traveled from the right-angle double mirror on one end side to the other end between the parallel plane mirrors. When the two parallel mirror surfaces configuring the parallel plane mirrors are disposed to be parallel to the z-x plane of the x-y-z axial coordinate system, the two reflection surfaces configuring the right-angle double mirror are perpendicular to the x-y plane, and the laser light entering at the angle φ of incidence crosses the x-y plane at a specific angle [[φz]].
