The rapid development of wearable electronics needs flexible conductive materials that have stable electrical properties, good mechanical reliability, and broad environmental tolerance. Herein, ultralow‐density all‐carbon conductors show excellent elasticity high stability when subjected to bending, stretching, compression at strains, which are superior previously reported elastic conductors, demonstrated. These fabricated from carbon nanotube forms, with their joints being selectively welded by amorphous carbon. joint‐welded foams a robust 3D network fixed nodes mobile segments, thus stabilities. They can readily scale up, presenting new type nonmetal conductor for many possible applications.
