A light emitting device for body hair comprises a light source unit which outputs light, and a control unit which controls output of the light source unit. The control unit controls the output of the light source unit such that an output light of the light emitting device for body hair through output from the light source unit has a main peak area which has an output light peak that indicates maximum intensity within a wavelength range of 1350 nm to 1550 nm, and such that an integral value of a peak area short wavelength component which is the main peak area component on a short wavelength side of the output light peak is greater than an integral value of a peak area long wavelength component which is the main peak area component on a long wavelength side of the output light peak.
