A biopotential measurement device (1b) is for measuring the biopotential of a user (10). The biopotential measurement device (1b) is provided with: a biopotential amplification unit (14) that differentially amplifies a biopotential detected by a reference electrode (49) and a measurement electrode (48) brought into contact with the user (10), and performs A/D conversion thereon; a biopotential output unit (15) that outputs the biopotential converted into a digital signal; a power supply unit (220) that supplies electric power to the biopotential amplification unit (14) and/or the biopotential output unit (15); and an electrostatic capacitance (201) equipped with a capacitance electrode to which a wire as a shield member (200) covering the perimeter of the measurement electrode (48) is connected. The ground potential of the power supply unit (220) is electrically connected to the ground potential of the electrostatic capacitance (201).
