The present invention provides a low-cost piezoelectric cable and wire harness using the same, which offer a high connection reliability without picking up interference signals in areas where the cable acts as a sensor. Coaxial piezoelectric cable 10 has a piezoelectric material layer 14 disposed between a core conductor 12 and an outer conductor 16. Piezoelectric material layer 14 is polarized and shows piezoelectric properties in a region 20 which extends along a window frame 2 of an automobile, but is not polarized, and therefore shows no piezoelectric properties, in a region 22 in which it is not desired that the cable act as a sensor. Accordingly, there is no pick-up of false signals in the region 22.
