<p>Provided is a method for producing a glass flake having a smooth surface and the desired thickness by a simple means in comparison to the prior art. The method for producing a glass flake comprises a step A for introducing gas from a nozzle disposed in molten glass to the molten glass so that a bubble that has adhered the nozzle tip will form inside the molten glass; a step B for continuing to introduce gas from the nozzle to the bubble formed inside the molten glass in order to increase the volume of the bubble until the bubble is brought to the liquid surface such that the portion of the bubble that has reached the liquid surface forces the molten glass at the liquid surface above the liquid surface level of the molten glass and a dome-shaped body wherein a portion of the bubble is contained inside the molten glass is formed on the liquid surface of the molten glass; a step C for bursting the dome-shaped body to form a glass flake; and a step D for suctioning and recovering the glass flake.</p>
