Provided are a composition, a conductive material, and a method of manufacturing the same, in which the composition and the conductive material have biocompatibility, can be used in the living body for a long period of time, have superior followability to the shape of wrinkles of an organ or the like, and can form a far superior interface with an organ or the like. The composition includes a carbon nanomaterial that is covered with molecules constituting a hydrophilic ionic liquid, in which the carbon nanomaterial is dispersed in a water-soluble polymer medium, and the carbon nanomaterial is doubly covered with the molecules constituting the ionic liquid and a water-soluble polymer.
