Disclosed is a biosignal measuring apparatus. The disclosed biosignal measuring apparatus comprises a sensor electrode including a taper unit that is tapered toward one end and a protrusion that is extended from the one end of the taper unit and is in contact with a body part to sense a biosignal, and a sensor supporting unit which supports a sensor electrode so that the sensor electrode keeps in contact with the body part. A main body can be connected to the sensor supporting unit and put on a body part. The present invention is designed to provide a biosignal measuring apparatus capable of stably measuring an electrical biosignal despite the movement of a body while maintaining a sensor contact at a constant pressure.
