Abstract:
A touch type input terminal that includes a base substrate, a piezoelectric sensor and an electrostatic sensor which are flat membrane-shaped, respectively. The electrostatic sensor includes a plurality of segment electrodes on a first main surface of a base film and a plurality of common electrodes on a second main surface. The piezoelectric sensor includes a piezoelectric film formed of PLLA drawn uniaxially. Displacement detecting electrodes are formed on a third main surface of the piezoelectric film so as to divide the third main surface into four portions. Displacement detecting electrodes are formed on a fourth main surface of the piezoelectric film so as to be opposed to the displacement detecting electrodes on the third main surface.
