Zusammenfassung:PROBLEM TO BE SOLVED: To prevent slight drop of the sensitivity of a neutron detector to neutrons in the initial stage by applying a neutron sensitive material to electrodes after a neutron absorbing material having a specific neutron absorption cross section is mixed at specific reactivity. SOLUTION: The neutron sensitive material 3 is applied to a high-voltage electrode 1 and signal electrode 2 after a neutron absorbing material 4 having a neutron absorption cross section of about 50-1,000 barn is mixed in the material 3 at a mixing ratio of, for example,
