[Problem] To provide an electrode pad, for use on a living organism, that can measure an electrocardiographic signal without being hindered by body-motion noise.[Solution] An electrode pad, for use on a living organism, that is attached to the skin of said living organism, detects an electrical signal, and supplies said electrical signal to an electrocardiograph. Said electrode pad for use on a living organism is characterized by the provision of a mesh-like electrode that extends along the skin, a conductive gel sheet that is layered on top of the electrode and extends along the surface of the skin, and a soft protective sheet that covers the layered electrode and conductive gel sheet.
