The present invention provides an easy-to-handle biological information measuring device that can easily superimpose an image diagnosis result and a biomagnetic measurement result with good accuracy. The biological information measuring apparatus (1) of the present invention includes a biomagnetic detection unit (2) capable of detecting the biomagnetism of the subject (S) and an image corresponding to the irradiated radiation as digital image data by supplying power. The radiation detection part (3) which can be acquired is arrange positioned, and a radiation detection part (3) is arrange positioned between the measurement area region of a subject (S) and a biomagnetism detection part (2). Moreover, it is preferable that the radiation detection unit (3) includes a control unit (6) that can be controlled so as not to supply power while the biomagnetism detection unit (2) detects biomagnetism.本発明は、画像診断結果と生体磁気計測結果とを良好な精度でかつ簡便に重ね合わせることが可能であり、取り扱いやすい生体情報計測装置を提供する。 本発明の生体情報計測装置（１）は、被検体（Ｓ）の生体磁気を検出可能な生体磁気検出部（２）と、照射された放射線に応じた画像を、電源供給によってデジタル画像データとして取得可能な放射線検出部（３）とを備え、放射線検出部（３）は、被検体（Ｓ）の計測領域と生体磁気検出部（２）との間に配置される。また、生体磁気検出部（２）が生体磁気を検出している間、放射線検出部（３）には電源供給を行わないように制御可能な制御部（６）を備えることが好ましい。
