[Problem] To provide a biological signal measuring device which is capable of measuring contact resistance with high precision. [Solution] The biological signal measuring device according to the present technology comprises a voltage source, a measuring electrode, a resistor, a first amplifier and a neutral electrode. The measuring electrode is connected to the voltage source and contacts a living body. The resistor is connected between the voltage source and the measuring electrode. The first amplifier amplifies an electric potential between the resistor and the measuring electrode. The neutral electrode contacts the living body. |
