Abstract: Provided is a conductive elastic band that can obtain vital information in smart clothes, wearable computers, or bio-shirts, can transfer the obtained vital information externally through a communication network, and can be applied to various kinds of fabrics and clothes while maintaining conductivity and flexibility in shape. The conductive elastic band includes a front surface in contact with the user including a conductive portion having a fabric electrode and a non-conductive portion weaved with general fibers, a non-conductive rear surface weaved with the general fibers and elastic warps located between the front surface and the rear surface.
