PROBLEM TO BE SOLVED: To manufacture a piezoelectric element which relaxes the microscopic internal strain that the sintered piezoelectric material has. SOLUTION: This is a piezoelectric element consisting of a piezoelectric substance which includes a pair of external electrodes and piezoelectric material and conductive material arranged between the external electrodes, and the piezoelectric material and the conductive material are laminar as a piezoelectric layer and a conductive layer, respectively, and the piezoelectric layers and the conductive layers are stacked alternately in the direction of connecting the external electrodes in a pair with each other, and besides the conductive layer is insulated from the internal electrode, and also, the thickness is 1μor under, and this piezoelectric element relaxes the internal strain, and a large quantity of strain can be obtained.
