Abstract
A biological information measurement device according to an embodiment of the present disclosure includes a control section that controls a first connection and disconnection and a second connection and disconnection, thereby inputting, to an AD conversion section, a plurality of first analog signals for changes in impedance or conductance between electrodes of individual electrode pairs and a second analog signal for a change in impedance or conductance between the electrodes of a plurality of the electrode pairs.
