<p>The present invention provides a piezoelectric sensor that, while responding to a request for increased compactness and lightness of weight, can have a reduced number of components and number of assembly steps, and can suppress production cost. The present invention is a piezoelectric element resulting from bending, along at least one bending line, a laminate containing an insulating film, a piezoelectric body layer provided to one primary surface of the insulating film, a first electrode layer provided to the piezoelectric body layer at the surface at the reverse side of with respect to the insulating film, and a second electrode layer provided to the other primary surface of the insulating film, and is characterized in that a portion of the first electrode layer and a portion of the second electrode layer are exposed at one primary surface of the piezoelectric element.</p> |
