An electrode apparatus for monitoring ECG includes: a sensing area consisting of graphite: a metal member which is attached to the rear surface of the graphite to transmit sensed information； a transmission line which is connected to the metal member and an ECG terminal in order to transmit the sensed information； a support member for supporting the metal member and the graphite； a silicon part of which the rear surface is coated with silicon； and an adhesive patch which has an adhesive material on the inner surface so that the electrode apparatus can be compressed and fixed to a user's skin.
