The present invention discloses a stove burner. The present invention, by designing the outer-ring fire cover body and the outer fire-spraying ring into two independent structures, enables the outer-ring fire cover body to be made of a heat-resisting material of low price, which reduces the manufacturing cost of the entire stove burner; besides, with the outer edge of the annular cover body plate in contact with the top of the outer fire-spraying ring and the cover body ring attached to the sidewall of the inner ring tube close to the gas inlet tube, this structure can better achieve good airtightness of the annular chamber.
