1. A piezoelectric device comprising:

  • a piezoelectric element comprising at least one piezoelectric body comprising a piezoelectric polmer film having electrodes on both main surfaces thereof;

    an inputting unit for inputting predetermined information to said piezoelectric element;

    a memory for storing temperature dependency information comprising an amount of displacement when a voltage is applied and an amount of deflection when a stress is applied to said piezoelectric element;

    a temperature detector for detecting an ambient temperature; and

    a correction unit for correcting the input information of said inputting unit based on a detected temperature result of the temperature detector and said temperature dependency information.
