The present invention provides a red phosphor that increases the reflectance of a green region, a method for manufacturing the same, and a white light source, a lighting device, and a display device using the same. The red phosphor of the present invention is characterized by containing an alkaline earth metal element (A), europium (Eu), silicon (Si), aluminum (Al), oxygen (O), and an atomic ratio of the following formula (1). Nitrogen (N) contains carbon (C) in the composition, (In formula (1), m, n, x, and y respectively satisfy 3 <m <5, 0 <n <10, 0 <x <1, 0 <y <2), and the alkaline earth metal element (A ) Contains at least barium (Ba). |
