  "textContent": "Provided are a laminated piezoelectric element which is equipped with a covered layer that is capable of alleviating a stress generated by expansion and contraction of a laminated body and is prevented from peeling off even due to a long drive, a manufacturing method thereof, an injection device equipped with the laminated piezoelectric element, and a fuel injection system. The laminated piezoelectric element has laminated body (7) which is formed by laminating a plurality of piezoelectric layers (3) and a plurality of internal electrode layers (5) and causing part of end faces of the internal electrode layers (5) to reach a side surface thereo. On the side surface of the laminated body (7), a pair of external electrodes (8) is alternatively electrically connected to the internal electrode layers (5) every other layer. In at least part where the pair of external electrodes (8) is not provided, an inorganic material layer (11) is adhered to the side surfaces of the laminated body (7) so as to cover the end surfaces of the internal electrode layers (5), and between the inorganic material layer (11) and the side surface of the laminated body (7), air holes (12) are formed.",
