Abstract: A piezoelectric shock sensor includes a lower cover, a piezoelectric element in which first and second piezoelectric sheets are stacked, and an upper cover. Each of the first and second piezoelectric sheets has a cantilever portion and a frame portion formed integrally with each other. First and second internal electrodes are formed on the first and second piezoelectric sheets, respectively. First and second lead portions, respectively electrically connected to the first and second internal electrodes, are exposed through opposing side surfaces of the piezoelectric element.
