Abstract: A method for producing a fluoride fluorescent material including: preparing a first solution containing manganese, a second solution containing at least one cation selected from the group consisting of K+, Li+, Na+, Rb+, Cs+, and NH4+, and a third solution containing at least one element selected from the group consisting of the elements from Groups 4 and 14 of the periodic table, and adding the first and third solutions dropwise, each at a rate of 0.3% or less of the total volume of the solution per minute to the second solution to obtain particles having a composition represented by formula (I): A2[M1-αMn4+aF6] (I) wherein A denotes at least one cation selected from the group consisting of K+, Na+, Rb+, Cs+, and NH4+; M denotes at least one element selected from the group consisting of the elements from Groups 4 and 14 of the periodic table; and a satisfies 0.04
