PROBLEM TO BE SOLVED: To provide a method for producing glass flakes having a smooth surface and a desired thickness by a simple means compared to the prior arts. SOLUTION: The method for producing glass flakes comprises: a step A for introducing a gas from a nozzle 3 disposed in a molten glass 1 into the molten glass 1 so as to form a bubble adhered to the tip of the nozzle 3, provided in the molten glass 1; a step B for continuing to introduce the gas from the nozzle 3 into the bubble formed in the molten glass 1 in order to increase the volume of the bubble and to allow the bubble to reach the liquid surface, so that a portion of the bubble that has reached the liquid surface pushes out the molten glass at the liquid surface in higher direction than the liquid surface level of the molten glass 1, forming a dome-shaped body, wherein a portion 6' of the bubble is included in the molten glass 1, on the liquid surface of the molten glass 1; a step C for bursting the dome-shaped body 7 to form glass flakes; and a step D for sucking and recovering the glass flakes.
