Abstract
The invention provides an elastic conductor which is excellent in stretchability and hardly causes a decrease in conductivity even when stretched. The elastic conductor includes an elastomer and two types of conductive particles, wherein the two types of conductive particles are flake-like particles and nanoparticles, and the conductive particles are dispersed throughout the elastomer.
