PURPOSE: To provide the subject instrument which can exactly measure the metabolic information at the plural points of a biotissue in a short period of time.
CONSTITUTION: A probe 6 provided freely movably along an axial direction is provided in a catheter 4 which is provided with a light transparent part 5a and a light shielding part 5b along the axial direction and has flexibility. An irradiating surface 7a which is provided along the axial direction and emits inspecting light and a photodetecting surface 8a which receives the inspecting light are provided in this probe 6. The inspecting light projected from the irradiating surface 7a transmits the biotissue while scattering and reflecting. The reflected light is received by the photodetecting surface 8a but the reflected light which does not contain the metabolic information is shielded by the light shielding part 5b and is prevented from being received from the photodetecting surface 8a.
