    摘要: There is provided a laminated piezoelectric ceramic element manufacturing method, wherein, even when the number of internal electrode laminations is increased, the lamination and cutting steps can be simplified, to enhance cutting precision and make cutting cost low. A first laminated body having stripe-like internal electrodes is cut into a plurality of second laminated bodies so as to have a width-direction dimension W corresponding to a width dimension of a laminated piezoelectric ceramic element chip to be ultimately obtained. Two or more second laminated bodies are laminated in the laminating direction to obtain a third laminated body, and the third laminated body is cut in the laminating direction and parallel to the width direction W to obtain a laminated piezoelectric body.

    摘要: A pyroelectric ceramic composition contains a compound represented by (Pb1-xCax)(1+a){(Ni1/3Nb2/3)yTi(1-y)}O3 (wherein x, y, and a satisfy 0.20≦x≦0.27, 0.01≦y≦0.06, and 0.001≦a≦0.02, respectively) as a main component and 0.3 to 2.5 mol of Mn per 100 mol of the main component. The amount of segregates containing Ni, Ti, and Mn is 1.0 vol % or less (including 0 vol %) of a fired sinter. A pyroelectric ceramic composition that has an adequately low insulation resistance and a high Curie temperature while achieving satisfactory pyroelectric properties is realized. Since the composition has a high Curie temperature, a thin, small pyroelectric element that withstands a reflow process can be obtained. Since the composition has a low insulation resistance, an infrared detector incorporating a pyroelectric element composed of the composition does not require a load resistance to be provided in parallel to the pyroelectric element and size reduction is possible.
