A stretchable raised electrode having a stretch property that can be used as a biological electrode for collecting biological signals while being pressed against a body is provided, and a method of manufacturing the stretchable raised electrode is provided. This raised electrode is a raised electrode formed by raising a surface of a sheet material having the stretch property. This raised electrode includes: a resin layer configured to be stretchable to follow the surface of the sheet material; and a plurality of conductive fibers each having an inserted portion, one end of which is inserted into the resin layer. The conductive fibers that are adjacent to one another are electrically in contact with one another at non-inserted portions into the resin layer, and the conductive fibers are formed in the resin layer so as to have such a density as causing an in-plane isotropic electric conductivity of an electrode region of the sheet material in which the conductive fibers are formed. This raised electrode can be obtained by an electrostatic spraying method.
