PROBLEM TO BE SOLVED: To provide a biological examination apparatus and a biological examination method capable of noninvasively achieving health degree determination of hair of a living body as it is on the skin without removing it from the skin.SOLUTION: A biological examination apparatus according to the present embodiment comprises a light irradiation unit, a detection unit, and a calculation unit. The light irradiation unit emits red light or near infrared light to the inside of a subject from a surface of the subject. The detection unit detects the light which transmits through the inside of the subject and is radiated from a surface of the subject to the outside. The calculation unit uses the radiated light to discriminate a first region of the subject where a light absorber exists, the light absorber localizing in the inside of the subject and affecting the intensity of the light transmitting through the inside of the subject and a second region of the subject where the light absorber does not exit, and measures a radiation intensity distribution of the light in the second region.【課題】脱毛することなく生えた状態のままで生体毛髪の健康度判定等を非侵襲に実現することができる生体検査装置及び生体検査方法を提供すること。【解決手段】 本実施形態に係る生体検査装置は、光照射部と、検出部と、計算部とを具備する。光照射部は、被検体表面から当該被検体内に向けて、赤色光又は近赤外光を照射する。検出部は、前記被検体内を伝播し当該被検体表面から外部へ放射される光を検出する。計算部は、前記放射された光を用いて、前記被検体に局在し且つ当該被検体内を伝播する光の強度に影響を与える光吸収体が存在する第１の領域と、前記被検体において前記光吸収体が存在しない第２の領域と、を分別し、前記第２の領域で光放射強度分布を測定する。【選択図】 図７
