Abstract
A detecting device of the present disclosure includes a first light-emitting unit that emits first light having a green wavelength band, a second light-emitting unit that emits second light having a wavelength band higher than the green wavelength band, a first light-receiving unit that receives the first light emitted from the first light-emitting unit and emitted from a biological body, and a second light-receiving unit that receives the second light emitted from the second light-emitting unit and emitted from the biological body, in which the first light-receiving unit includes a bandpass filter that selectively transmits the first light, and a distance from the first light-emitting unit to the first light-receiving unit is shorter than a distance from the second light-emitting unit to the second light-receiving unit.
