Multilayer pyroelectric element

A multilayer pyroelectric element comprising:

• a laminate body constituted by multiple pyroelectric body layers laminated in a thickness direction;
• internal electrode layers which are provided between the pyroelectric body layers of the laminate body, wherein one ends of the internal electrode layers extend to outer peripheries of adjoining pyroelectric body layers;
• and
• external electrodes that connect the alternate internal electrode layers together at the one ends;
• wherein said multilayer pyroelectric element has:
• a pair of first faces opposing to each other, a pair of second faces opposing to each other, and a pair of third faces opposing to each other, wherein each pair is provided on a plane intersecting planes on which the other pairs are provided, respectively, where, when a distance between the first faces is given by x1, a distance between the second faces is given by x2, and a distance between the third faces is given by x3, then relationships of
• x1/x3≥1 AND x2/x3≥1
• are satisfied,
• wherein each external electrode is provided on a roughly entire area of each third face running parallel with a laminating direction of the pyroelectric body layers.
