Abstract: Provided are a fluorescent material with excellent durability, which emits red light, a method of producing the same, and a light emitting device. The fluorescent material is a fluorescent material including a fluoride-containing fluorescent material core comprising Mn, at least one element selected from the group consisting of an alkali metal element and NH4+, and at least one element selected from the group consisting of a Group 4 element and a Group 14 element in a composition thereof; and at least one of an aluminum hydroxide particle and a calcium hydroxide particle as disposed on a surface of the fluorescent material core.
