Abstract: An oxychloride phosphor of the present disclosure includes divalent Eu arranged as an augmenting agent, at part of locations. The locations correspond to site of at least two kinds of predetermined substances included in a host crystal. A rate of the number of the divalent Eu with respect to the sum of the number of moles of the predetermined substance and the number of moles of the divalent Eu is less than 2%. When the predetermined substance is represented by A, the oxychloride phosphor is represented by a general formula of xAO.yEuO.SiO2.zCl. In this formula, A represents Sr and Ca, or Sr, Ca, and Mg, y indicates a value of not less than 0.002 and not more than 0.02, x+y indicates a value of more than 1.00 and not more than 1.30, and z indicates a value of not less than 0.20 and not more than 0.70.
