PROBLEM TO BE SOLVED: To provide a light pulse multiplexing unit capable of separating spatially a signal light pulse, without differing a propagation direction with a wavelength included in the signal light pulse, and capable of imparting a time lag, and a time resolution measuring instrument using the same. SOLUTION: This light pulse multiplexing unit includes: a half-mirror 1 for photo-demultiplexing an incident light to generate a transmission light and a reflected light; and mirror units MU1-1 or the like arranged opposedly to both sides of the half-mirror 1, for deflecting respectively the transmission light and the reflected light photo-demultiplexed by the half-mirror 1, and for multiplexing in a common portion on the half-mirror 1, wherein each mirror unit MU1-1 or the like has two mirrors M1-11, M1-12; and further includes: a mirror unit space regulating stage ST for making variable a space between the pair of opposedly arranged mirror units; and a mirror space regulating stage ST for making variable a space between the adjacent mirror units.
