Abstract
A living-body component measuring apparatus measures a component of an inner tissue of a living body serving as an object to be measured by emitting laser light having two or more wavelengths from a light source and measuring reflected light of the laser light from the inner tissue of the living body. The living-body component measuring apparatus includes a beam splitter that changes optical paths of a part of the laser light and the reflected light, a reference-light measuring unit that measures, as reference light, the part of the laser light having the optical path changed by the beam splitter, a reflected-light measuring unit that measures the reflected light having the optical path changed by the beam splitter, and an analysis unit that analyzes the inner tissue by measuring a spectrum of the reflected light or the reference light.
