BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode pad, and more particularly, to a pad forming unit forming an external appearance of an electrode pad. An electrode unit provided on one surface of the pad forming unit and transmitting a shock shock to a human body; And a gel supplying unit connected to the electrode unit and containing a gel for allowing the electrode unit to be easily attached to the human body and configured to supply the gel to the surface of the electrode unit under predetermined conditions And is characterized by its constitution. According to the present invention, there is provided an electrode pad capable of supplying a gel and an defibrillator including the electrode pad, wherein the electrode pad includes a gel connected to the electrode pad and capable of being easily attached to a human body, The gel is supplied to the surface of the electrode part in the electrode part. Therefore, separate gel storage and gel application process are not necessary, and the preparation time is shortened. In general, the gel is not exposed, A predetermined amount of gel can be supplied so that a proper amount of gel can be supplied in a timely manner. According to the present invention, there is provided a gel dispenser comprising: a gel dispenser for dispensing a gel, a gel bag storing a gel, a gel stored in a gel bag, between a surface of the electrode and a skin of a human body, Wherein the opening and closing member includes a thread bundle of the gel discharge port, or is configured by an electronic door, so that the gel discharge can be easily controlled. In addition, according to the present invention, a gel is formed in at least one or more granules enclosed in a gel in a gel supply portion, and the gel is released when the predetermined pressure is applied to the gel so that the gel is not exposed at normal times , Even application of the gel becomes possible.본 발명은 전극 패드에 관한 것으로서, 보다 구체적으로는 전극 패드의
