PROBLEM TO BE SOLVED: To provide a spectrophotometer which measures and analyzes a trace amount of sample, without using a sample cell, employs a unique mechanism and a simple structure that has not been available so far. SOLUTION: The structure of the spectrophotometer consists of: a light source A for irradiating the sample S with measuring light; a sample-holding part B for holding the sample S; and a detection part C for detecting the measuring light transmitted through the sample S. The sample-holding part B is equipped with: a pair of rotating drums 7, arranged so that the rotational axes of them are set parallel and rotated in synchronism, in mutually reverse directions; and fiber rods 8, which comprise a light transmissive material, respectively arranged to the peripheral walls of the rotating drums 7, in a state with one-end surfaces of them being directed toward the direction of radiation. The sample S is held between the end surfaces of the left and the right fiber rods 8, by rotating the rotating drums 7; and the measuring light is made to pass through the left and the right fiber rods 8, which hold the sample in the axial direction of the fiber rods 8.
