A laminated piezoelectric element has excellent suppression effect on characteristics deterioration caused by a pyroelectric effect. Inside an element main body are a first internal electrode, a piezoelectric layer, and a second internal electrode that has different polarity from the first internal electrode, which are repeatedly layered a plurality of times along the lamination direction. A first external electrode is formed on a first side surface of the element main body. A second external electrode is formed on a second side surface of the element main body. A resistance layer connected to the internal electrodes is formed in at least part of a third side surface of the element main body in which the internal electrodes are exposed. An insulating layer is formed on a third side of the element main body so as to cover the resistance layer.
