PROBLEM TO BE SOLVED: To provide a flame detector capable of highly accurately detecting a flame by eliminating a source of misinformation and filtering out noise. SOLUTION: The flame detector detecting a generated flame in the event of fire by detecting a light of a wavelength specific to the flame is provided with a plurality of light detecting means detecting a plurality of lights of different wavelengths one another specific to the flame and outputting a detection signal according to each wavelength, a calculating means calculating a normalized correlation value between each of waveforms for each detection signal detected by the plurality of the light detecting means and a ratio of a moving average between each of waveforms for each detection signal, and a flame generation deciding means deciding as the flame is generated when the normalized correlation value and the ratio value of the moving average calculated by the calculating means respectively fall within prescribed ranges.
