1. A piezoelectric generator for causing strains in a piezoelectric element by external forces or vibrations to generate electrical energy comprising:

  • a flat base plate;

    an elastic plate, which is bent in an arc shape and is attached to said base plate at both ends thereof so that a space is created to allow the elastic plate to deform between it and the particular base plate; and

    a spacer member having a fulcrum, which is located between one of the fixed ends of the particular elastic plate and the peak point of said arc-like curve for supporting said elastic plate in the vicinity of said one end of thereof, the spacer member being provided to form a space between its side opposite to the base plate and said elastic plate for allowing the elastic plate to deform;

    whereinsaid piezoelectric element is glued to at least one of the front and back surfaces of said elastic plate.
