Fig. 1 is a perspective view showing a state where a polarization voltage is applied to the main surfaces of a plurality of sheets of piezoelectric rubber to generate polarization in the same direction, Fig. 2 is a perspective view showing a state in which these are laminated, and Fig. 3 The figure is an enlarged sectional view of just one fragment, Figures 4 and 5 are perspective views showing the polarization generation state in the separated state when cable-shaped piezoelectric rubber is laminated and bonded, and Figure 6 is the structure in the laminated state. FIG. 7 is a sectional view thereof, and FIGS. 8 and 9 are perspective views of a conventional sheet-like piezoelectric rubber and a cable-like piezoelectric rubber, respectively. 1, 11, 14...piezoelectric layer, 2, 3, 12, 1
3, 15, 16...electrode layer.
