An electrically conductive yarn (1) includes a plurality of individual filaments (2) and an electrically conductive portion (3) that covers surface of the individual filaments (2). The electrically conductive portion (3) contains a carbon-based material, in particular carbon nanotubes, a binder, and a metal. The electrically conductive portion (3) has a network structure in which the carbon nanotubes are connected to one another and is constituted such that the metal is interspersed within the network structure. The electrically conductive portion (3) may further contain Al2O3.
