Provided is a neutron scintillator that has excellent neutron detection efficiency and neutron-gamma discrimination, has uniform properties, and can easily be made in large sizes. The neutron scintillator includes a resin composition in which eutectic particles are contained in a resin with a similar refractive index, the eutectic particles having a sphere equivalent diameter of about 50 μm to 1000 μm and including lithium fluoride and inorganic fluorescent materials such as MgF 2 , CaF 2 , and SrF 2 which include, as a luminescent center atom, a lanthanoid such as Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb. |
