To obtain a crystallized glass member having a curved shape and provide a method for producing the same. A method for producing a crystallized glass member having a curved shape, including a deformation step for adjusting the temperature of a plate glass to a first temperature zone from higher than [At+40]° C. to [At+146]° C. or lower, where At is the yield point (° C.) of the plate glass and deforming at least part of the plate glass into a curved shape by external force acting on the plate glass while precipitating crystals from the plate glass.
