The object of the present invention is to provide a flame hole unit structure of a pre-mixed gas burner, wherein a plurality of punching plates can be manufactured relatively easily and are stacked such that various shapes of flame holes are implemented in a three-dimensional manner whereby a pre-mixed gas burner can stably maintain flames in the wide range of operation and prevent combustion noise, and further, the pre-mixed gas burner is easily manufactured. To achieve this objective, the present invention provides a flame hole unit structure of a pre-mixed gas burner having a plurality of flame holes through which mixed gas of gas and air is sprayed to form flames, wherein: a plurality of flame hole plates are punched such that holes of a certain shape are arranged in predetermined patterns; and said plurality of the flame hole plates are stacked to form flame holes of different sizes and shapes. |
