Provided are a biometric information measuring device, a biometric information measuring method and a biometric information measuring program with which it is possible for blood flow information to be measured accurately while detecting pressure pulse waves necessary for measuring biometric information. This biometric information measuring device 100 is provided with: a pressing mechanism 5 which presses a pressure sensor 1 against a living body； a pressing force control unit 31 which controls a pressing force applied by the pressing mechanism 5； a blood flow sensor 2 which is disposed adjacent to the pressure sensor 1； a signal processing unit 2A which measures blood flow information on the basis of an output signal from the blood flow sensor 2； and a control unit 3 which, on the basis of the blood flow information and pressure pulse wave information measured during a pressing force control period during which the pressing force was being increased, determines a first pressing force applied by the pressing mechanism 5, and records in a memory 4 a pressure pulse wave detected by the pressure sensor 1 in a first state in which the pressing force is controlled to the first pressing force, and blood flow information measured in the first state.L'invention concerne un dispositif de mesure d'informations biométriques, un procédé de mesure d'informations biométriques et un programme de mesure d'informations biométriques avec lesquels il est possible de mesurer des informations de circulation sanguine avec précision tout en détectant des ondes de pression nécessaires pour mesurer des informations biométriques. Ce dispositif de mesure d'informations biométriques 100 est pourvu : d'un mécanisme de pressage 5 qui presse un capteur de pression 1 contre un corps vivant ； d'une unité de commande de force de pressage 31 qui commande une force de pressage appliquée par le mécanisme de pressage 5 ； d'un capteur de circulation sanguine 2 qui est disposé de manière adjacente au capte
