PROBLEM TO BE SOLVED: To provide a biological measurement apparatus and a biological measurement method of a probe system capable of improving uniformity of measurement sensitivity.SOLUTION: A plurality of light irradiation parts 2c and a plurality of light reception parts 2d constitute gratings of intervals d on a contact surface 2a of a probe. A part of the plurality of light reception parts 2d are located separated from the light irradiation parts 2c in an X direction and a Y direction by a distance A×d (A being an integer of 2 or more), and a part of a plurality of light reception parts 2d are located separated in the X direction and the Y direction by the distance A×d. An operation part calculates internal information based on the result of detection of the measurement light obtained by a combination of the light irradiation part 2c and the light reception part 2d separated by the distance (A×d) in the X direction, and a combination of the light irradiation part 2c and the light reception part 2d separated by the distance (A×d) in the Y direction.SELECTED DRAWING: Figure 2 【課題】計測感度の均一性を向上できるプローブ方式の生体計測装置及び生体計測方法を提供する。【解決手段】プローブの当接面２ａにおいて、複数の光照射部２ｃ及び複数の受光部２ｄは、間隔ｄの格子を構成する。複数の受光部２ｄの一部は、光照射部２ｃからＸ方向及びＹ方向に距離Ａ×ｄ（Ａは２以上の整数）だけ離れて位置し、複数の受光部２ｄの一部はＸ方向及びＹ方向に距離Ａ×ｄだけ離れて位置する。演算部は、Ｘ方向に距離（Ａ×ｄ）だけ離れた光照射部２ｃと受光部２ｄとの組み合わせ、及びＹ方向に距離（Ａ×ｄ）だけ離れた光照射部２ｃと受光部２ｄとの組み合わせによって得られる計測光の検出結果に基づいて内部情報を算出する。【選択図】図２
