PROBLEM TO BE SOLVED: To provide a neutron diffracting device capable of detecting scattered neutrons by irradiating a neutron beam locally to a measuring sample, acquiring Bragg reflection data by moving the measuring sample successively, and performing observation by mapping acquired data. SOLUTION: A neutron beam for observation led out from a neutron source is allowed to pass the first slit, and guided into the second slit through a guide pipe formed from a neutron mirror, to thereby narrow the diameter of the neutron beam to be irradiated to the sample. A plurality of detection pipes for detecting scattered neutrons are aligned on a circular arc centered at the sample, and each shielding plate facing to the center is provided between each detection pipe. While moving a stand on which the measuring sample is placed at each prescribed interval by a moving mechanism, data of the detection pipes are acquired, and mapping data are acquired.
