ABSTRACT An electrode for an electrocardiograph used for measuring potentials of a number of points of a body surface near the heart and producing an isopotential map thereof, has a plurality of spring-loaded rods movably mounted for reciprocal movement in the direction of the lengths thereof and urged toward the human body surface, and a pin contact set on the one end of each rod. Each pin contact set has a plurality of parallel electrically conductive spring loaded pin contact, movably mounted for movement reciprocally in the direction of its length for directly contacting the human body surface. The pin contacts of each set are mounted in a small area close to one another and are mutually electrically connected in parallel, the space between the pin contacts of each pin contact set being much smaller than the space between the adjacent small areas of the pin contact sets, whereby the potential at a position on the body surface contacted by a pin contact set can be detected as long as one pin contact in the set is in good contact with the body, even if the other pin contacts in the set are in bad contact.
