In a flame photometric detector, an upper end of a nozzle for providing a mixed gas of a column outflow gas (sample) and a fuel gas is located at a position higher than an ejection port for a combustion supporting gas disposed around the upper end of the nozzle. The mixed gas is spouted from the upper end of the nozzle, and the combustion supporting gas is spouted from the ejection port to supply oxygen. According, light emission for causing noise resulting from impurities in the combustion supporting gas occurs at a lower side of the flame, and emission of light resulting from the components in the sample occurs at an upper side of the flame. Thus, the lights can be separated easily to measure the sample accurately.
