PROBLEM TO BE SOLVED: To provide a biological sensor module and a biological information measuring apparatus capable of improving detection accuracy of biological information.SOLUTION: A biological sensor module includes a light emission part for emitting an irradiation light to be irradiated onto a living body, a light reception part for receiving a reflection light of the irradiation light reflected by the living body, and a passage part through which the irradiation light and the reflection light pass. The passage part includes an outer surface part that comes in contact with the living body, and an inner surface part having a front-back relationship with the outer surface part. The outer surface part includes a first convex curved surface for pressing the living body, and the inner surface part includes a second convex curved surface for condensing the reflection light incident in the passage part on the light reception part. When a direction from the light emission part to the light reception part is represented as a first direction, and a direction from the inner surface part to the outer surface part is represented as a second direction, a curvature radius of the second convex curved surface is smaller than a curvature radius of the first convex curved surface in a cross section parallel to a plane defined by the first direction and the second direction.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】生体情報の検出精度を高めることができる生体センサーモジュール及び生体情報測定装置を提供する。【解決手段】生体センサーモジュールは、生体に照射される照射光を出射する発光部と、照射光が生体にて反射された反射光を受光する受光部と、照射光及び反射光が通過する通過部と、を備え、通過部は、生体と接触する外面部と、外面部とは表裏の関係にある内面部と、を有し、外面部は、生体を押圧する第１凸曲面を有し、内面部は、通過部に入射された反射光を受光部に集光する第２凸曲面を有し、発光部から受光部に向かう方向を第１方向とし、内面部から外面部に向かう方向を第２方向とした場合、第１方向と第２方向とによって規定される平面と平行な断面において、第２凸曲面の曲率半径は、第１凸曲面の曲率半径より小さい。【選択図】図４
