A method for producing a fluoride fluorescent material comprises: preparing fluoride particles having a composition containing at least one element or ion A selected from the group consisting of alkaline metal elements and NH4+, at least one element M selected from the group consisting of Group-4 elements and Group-14 elements, Mn4+, and F, in which a molar ratio of A in 1 mol of the composition is 2, a total molar ratio of M and Mn4+ is 1, a molar ratio of Mn4+ is in a range of more than 0 and less than 0.2, and a molar ratio of F is 6; subjecting the fluoride particles to a first heat treatment at a temperature of 500° C. or more in an inert gas atmosphere; washing the first heat-treated fluoride particles with a washing liquid; and bringing the washed fluoride particles into contact with a fluorine-containing substance and subjecting the resulting fluoride particles to a second heat treatment at a temperature of 400° C. or more.
