PROBLEM TO BE SOLVED: To provide a cable-like pressure sensor which does not cause environmental pollution and superior in electrode stability. SOLUTION: The cable-like pressure sensor is constituted of both a flexible pressure-sensitive body 8 and a flexible external electrode 9. The flexible pressure-sensitive body 8 is made of both an organic polymer and ceramic piezoelectric particles having a bismuth layer-like structure not containing lead, and the flexible external electrode 9 is formed by forming metal layers on both surfaces of an electric insulating flexible support and wound on the flexible pressure-sensitive body 8. It is thereby possible to prevent environmental pollution, acquire electrodes having a stable electric resistance, and stably implement superior sensor characteristics. COPYRIGHT: (C)2005,JPO&NCIPI
