[Problème] Fournir un dispositif de mesure d'informations biologiques permettant de mesurer de façon fiable des ondes de pouls, des changements de battement pouls et d'autres informations biologiques sans recourir à des dispositifs surdimensionnés ou coûteux. [Solution] La présente invention concerne un dispositif de mesure d'informations biologiques qui est pourvu de : un élément d'émission de lumière pour émettre une lumière de mesure d'une longueur d'onde prédéterminée ; un élément de réception de lumière pour recevoir une lumière de retour à partir de la lumière de mesure par l'intermédiaire d'un sujet ; une unité de mesure d'informations biologiques pour mesurer des informations biologiques du sujet sur la base du résultat de la réception de lumière par l'unité de réception de lumière ; une unité de commande d'émission de lumière pour amener l'élément d'émission de lumière à émettre la lumière de mesure à des temps séparés par des intervalles prédéterminés ; et une unité de détermination de fixation qui, lorsque la lumière de mesure est émise aux intervalles prédéterminés sous le contrôle de l'unité de commande d'émission de lumière, détermine l'état de fixation au sujet sur la base de la quantité de lumière de retour, correspondant à la lumière de mesure pour chaque temps d'émission, reçue par l'élément de réception de lumière.
