PROBLEM TO BE SOLVED: To reduce possibility of erroneous irradiation of a laser beam used for acquisition of biological information.SOLUTION: A measuring apparatus comprises: a first light emitting section for emitting light of a first wave length； a second light emitting section having an invasion depth with respect to a measuring site exceeding that of the light of the first wave length, and emitting light of a second wave length； a light receiving section for generating a detection signal according to a light reception level of light reaching there from the measuring site； and an analysis section for acquiring biological information according to the detection signal. The first light emitting section, the second light emitting section, and the light receiving section are installed on a detection surface facing the measuring site. A distance between the first light emitting section and the light receiving section exceeds a distance between the second light emitting section and the light receiving section.SELECTED DRAWING: Figure 2【課題】生体情報の取得に使用されるレーザーの誤射の可能性を低減する。【解決手段】第１波長の光を出射する第１発光部と、測定部位に対する深達度が前記第１波長の光を上回る第２波長の光を出射する第２発光部と、前記測定部位から到達する光の受光レベルに応じた検出信号を生成する受光部と、前記検出信号に応じた生体情報を取得する解析部とを具備し、前記第１発光部と前記第２発光部と前記受光部とは、前記測定部位に対向する検出面に設置され、前記第１発光部と前記受光部との距離は、前記第２発光部と前記受光部との距離を上回る測定装置。【選択図】図２
