An electrode for applying to human skin, has an electrically non-conductive support. The support has on its upper side a projecting, electrically conductive connection element with a connection location for the releasable connection of a signal conductor. A conductor is provided, and the conductor is arranged at least to some extent on the opposite, underside of the support and is connected electrically to the connection element and to a contact medium, which is directed towards the skin. The connection element has at least one protrusion, which extends through the support and, at its end, has a widened region formed by deformation. This deformed, widened region makes it possible to establish, on the one hand, an electrical connection between the conductor and the connection element and, on the other hand, a mechanical fastening of the connection element on the support.

Provided is a wireless electrocardiogram monitoring device comprising: a patch part including a plurality of electrodes; and a module part detachably coupled to the patch part and capable of wireless communication with an external device, wherein the patch part comprises: a downward patch part formed at the bottom surface to be attached to the human body while some of the plurality of electrodes are exposed from the bottom surface; and an upward patch part disposed at the top surface opposite to the bottom surface while the others of the plurality of electrodes are exposed from the top surface.
