PURPOSE: A pre-mix burner with low-noise is provided to prevent noise because size and form of multiple flame holes are differently formed to prevent resonance in combustion. CONSTITUTION: A pre-mix burner with low-noise comprises a burner body unit(10). Multiple plates(110,120,130,140,150,160,170) are laminated to form the burner body unit and have a mixed gas passage and multiple flame holes(110c,120c,130c,140c,150c). Cut portions of the plates adjacent to each other are arranged across each other to form the mixed gas passage and the multiple flame holes. The flame holes in the upper part of the burner body unit are formed with different sizes.
