摘要

To provide a biological information measuring device for measuring a pulse wave of the artery and beating of the heart that a living body indicates with less physical burden on the living body for the measurement.SOLUTION: A biological information measuring device includes a belt 20 attached surrounding an upper limb part 90 of a living body 80 and a transmission/reception part 40 mounted on the belt 20 which is capable of transmitting and receiving a radio wave. The transmission/reception part 40 includes transmission antenna parts 41 and 43 for emitting radio waves E1 and E2 to the artery 91 of the upper limb part and the heart 81 respectively, and reception antenna parts 42 and 44 for receiving radio waves E1' and E2' reflected by a tissue 91a displaced accompanying the artery 91 of the upper limb part and/or a pulse wave of the artery, and a tissue 81a displaced accompanying the heart 81 and/or beating of the heart respectively. The biological information measuring device includes a biological information detection part 110 for acquiring a pulse wave signal PS1 indicating the pulse wave of the artery 91 of the upper limb part and a beating signal PS2 indicating the beating of the heart 81 based on the output of the reception antenna parts 42 and 44.SELECTED DRAWING: Figure 1
