Claims (4)

  1. Multiple first electrodes measure biological information in a portion of the right ear, Multiple second electrodes measure biological information in a portion of the left ear, It has a differential amplifier circuit, Two of the multiple potentials detected by the multiple first electrodes and the multiple second electrodes are selected based on the stability of the multiple potentials such that the noise contained in each of the two potentials is evaluated to be smaller. The differential amplifier circuit amplifies the difference between the two selected potentials in the biological information measuring device.
  2. The biological information measuring device according to claim 1, characterized in that the plurality of first electrodes or the plurality of second electrodes are dry electrodes in which a conductive film of silver chloride is formed on the outside of the plurality of first electrodes or the plurality of second electrodes.
  3. The biological information measuring device according to claim 2, characterized in that the dry electrode uses a polymer material, and the polymer material is coated with silver chloride.
  4. The biological information measuring device according to claim 1, wherein two of the multiple potentials detected by the multiple first electrodes and the multiple second electrodes are selected using the amplitude and/or change in amplitude of each of the multiple potentials as an indicator of the stability of the multiple potentials .
