Abstract: Provided are a phosphor which is capable of emitting green light of high luminance and in which unfavorable effects on other members has been reduced so as to be applicable to white light having excellent light emitting characteristics, a light emitting device using the phosphor, and a method for manufacturing the phosphor. The phosphor containing silicon, magnesium, and chlorine, and activated with europium and capable of emitting green light, in which the molar ratio of chlorine to magnesium is in a range of 1.0 ‰¤ Cl/Mg ‰¤ 1.9. Introduction of chlorine at such a composition ratio improves the light emitting characteristics and the amount of chlorine dissolved.
