The present invention provides a brominated flame retardant determining method that determines whether or not a brominated flame retardant is contained in a determination target object by emitting light to the determination target object composed of resin, receiving reflected light from the determination target object emitted with the light, calculating an absorption spectrum of the determination target object based on the reflected light, and determining whether or not a brominated flame retardant is contained in the determination target object in the absorption spectrum, based on an absorption spectrum in at least one of wavelength bands including a wavelength band of 1.42 µm or more and 1.44 µm or less, a wavelength band of 1.45 µm or more and 1.47 µm or less, a wavelength band of 1.66 µm or more and 1.68 µm or less, a wavelength band of 1.72 µm or more and 1.74 µm or less, a wavelength band of 1.92 µm or more and 1.94 µm or less, a wavelength band of 2.11 µm or more and 2.12 µm or less, a wavelength band of 2.17 µm or more and 2.20 µm or less, and a wavelength band of 2.31 µm or more and 2.34 µm or less.
