A fabric for detecting vital signals from human body includes a layer of fabric and electrically conductive yarns. The layer of fabric is formed of weft and warp electrically insulating yarns woven together. Electrically conductive yarns is woven in parallel with weft or warp electrically insulating yarns and interval-spaced from one another. Each of the electrically conductive yarns has a wave-shaped detecting section. All wave crests of the wave-shaped detecting section are protruded out of a surface of the layer of fabric while all wave troughs of the wave-shaped detecting section are woven within the layer of fabric. Each of electrically conductive yarns has its all wave crests misaligned in position with all wave crests of its immediately adjacent electrically conductive yarn. Each of electrically conductive yarns has its all wave troughs misaligned in position with all wave troughs of its immediately adjacent electrically conductive yarn.
