[Object] To provide a vital sign information measuring electrode that can measure vital sign information stably without using an electrically conductive gel.[Solution] A vital sign information measuring electrode 1 includes a substrate 10 and an electrode layer 20 disposed on a surface of the substrate 10, a part of the electrode layer serving as a contact portion that can come into contact with a living body. The contact portion 21 of the electrode layer 20 has a dispersion structure in which silver chloride and silver or a silver alloy are dispersed in a synthetic resin 52. In the contact portion 21 of the electrode layer 20, the content of silver chloride on a surface 21S side on which the contact portion 21 comes into contact with the living body is higher than the content of silver chloride on an inner side.
