Abstract
A biological material measuring apparatus includes an infrared light source unit to radiate infrared light in entirety or part of a wavelength region including absorption wavelengths of a biological material, a prism to cause the infrared light radiated from the infrared light source unit to pass therethrough and emit the infrared light to a living body surface while being in contact with the living body surface, a light source to radiate light of a wavelength in a visible light region or a near infrared region to the prism, and a light position detector to detect a path of light from the light source by detecting light from the light source which is emitted from the prism.
