A flexible conductive material includes an elastomer, a conductive agent filled in the elastomer, and an adsorbent fixed inside the elastomer and able to adsorb ionic material. With the flexible conductive material, ionized impurities are unlikely to transfer to an adherend such as a dielectric film. Thus, leakage current during application of voltage decreases. Accordingly, by forming an electrode and a wiring with the flexible conductive material, leakage current can be reduced, and a transducer and a flexible wiring board having excellent durability can be produced. In addition, using the flexible conductive material, an electromagnetic shield can be produced having a small leakage current.
