A laminated piezoelectric device comprising a device body 10 on which a number of piezoelectric layers 2 and internal electrodes 3, 4 are laminated, external electrodes 5, 6 electrically connected to the internal electrodes 3, 4 and formed on the surface of the device body 10, an insulation layer 7 and a resistance layer 8. The insulation layer 7 covers at least a portion wherein internal electrodes 3, 4 are exposed on the surface of the device body 10, where mechanical displacement is generated by applying voltage. The resistance layer 8 is formed to connect between external electrodes 5, 6 and has a lower electric resistance value than the insulation layer 7.
