1. A method for reviving an electrode unit of a biosensor device which includes a working electrode and a counter electrode, and which measures a concentration of an object substance based upon an electrical signal generated between the working electrode and the counter electrode when a predetermined forward measurement bias voltage is applied to the working electrode on which a physiologically active substance is placed, the electrical signal being generated based upon a biological reaction of the object substance, said method comprising the steps of:

  • (1) applying a predetermined reverse bias voltage to the working electrode for a predetermined time period, and(2) applying a predetermined forward measurement bias voltage to the working electrode,wherein at least one of the bias voltages is gradually increased in absolute value according to a time constant to reach a predetermined value.
