Disclosed is a measuring probe (40) wherein measuring light is inputted to single line fibers (13C, 14C, 15C) prior to being received by light-receiving sensors (13B, 14B, 15B) via interference film filters (13A, 14A, 15A). The interference film filters (13A, 14A, 15A) are formed such that transmissivity characteristics that correspond to measurement parameters are obtained under the conditions of intensity distribution with respect to the angle of incidence of the light inputted to the interference film filters (13A, 14A, 15A). Consequently, in the measuring probe (40), influence of fluctuation of the transmissivity characteristics due to the angle of incidence is reduced, while using the interference film filters (13A, 14A, 15A). |
