To provide an inorganic phosphor which emits light at low resistance and with high luminance and a light-emitting device using the same.

The inorganic phosphor has at least one kind selected from a group 12-16 compounds in the periodic table or a mixed crystal thereof as a parent material. The crystal structure comprises a wurtzite structure composed of the parent material and a halite structure composed of the parent material at a ratio of the halite structure to the wurtzite structure in the parent material of 0.1-10%. The light-emitting device uses the inorganic phosphor.
