PROBLEM TO BE SOLVED: To provide a neutron scintillator capable of detecting neutrons with high sensitivity and having little influence of background noise derived from γ rays, and a neutron detector using the neutron scintillator. A borate containing at least Mg and a divalent transition element (chemical formula Mg m B n O m + 3n / 2 (where m and n are positive integers) includes Cr, Mn , A scintillator for neutrons characterized by comprising a divalent transition element such as Fe, Co, Ni, Cu and Zn.
