<p>[Problem] To provide a laminated piezoelectric element which is suppressed in the occurrence of cracks in a laminate, an injection device which is provided with the laminated piezoelectric element, and a fuel injection system. [Solution] The present invention is characterized by comprising: a laminate (4) wherein a piezoelectric layer (2) and an internal electrode layer (3) are laminated; an external electrode (6) which is electrically connected to the internal electrode layer (3) and fixed to a lateral surface of the laminate (4), with a bonding material (5) being interposed therebetween, such that a part of the external electrode (6) extends beyond one end face of the laminate (4) in the lamination direction; and a fixing member (7) which is formed of a metal and is in contact with the one end face of the laminate (4), while being at a distance from the external electrode (6). The present invention is also characterized in that the external electrode (6) has a bent portion (61) that is bent so as not to come into contact with the one end face of the laminate (4).</p> |
