A gas burner is provided to prevent the second mixture gas outburst flame hole from being stopped by installing the inner and outer burner upper covers at the upper part of the inner and outer burner bodies. A gas burner is composed of an inner burner unit(10) having an inner burner body(11) formed with a first gas space(11a) containing a first mixture gas outburst flame hole(11a-1) where the gas is discharged by dividing the inner side by a partition(11c) along the circumferential direction and a second air tank(11b) containing a second air injection hole(11b-1) where the air is injected, a first air tank(12) formed with first plural air injection holes(12a) at the upper surface to discharge the air blown from a blowing fan(30) in the center of the inner burner body to the upper side, and an inner burner upper cover(13) mounted at the upper side of the inner burner body and formed with a first flame outburst unit(13a) at the center, wherein the flame combusted through the first flame outburst unit is exhausted; an outer burner unit(20) comprising an outer burner body(21) formed with a second mixture gas outburst flame hole(21a-1) to supply the gas to a second gas space(21a) formed inside and to exhaust the gas to the upper surface, and an outer burner upper cover(22) mounted at the upper surface of he outer burner body and formed with a second flame outburst unit(22a) at the center, wherein the flame combusted through the second flame outburst unit is exhausted; the blowing fan for blowing the air by a driving motor(32); and a gas pipe supplying the gas to the first and second gas spaces.
