摘要： Provided is a multilayer ceramic capacitor having a capacitor body formed by alternately laminating a dielectric layer and an internal electrode layer, and an external electrode formed on both ends of the capacitor body. The dielectric layer has at least two type of barium titanate crystal grains that differ from one another in at least one selected from Ca composition concentration, Sr composition concentration, and Zr composition concentration, and a grain boundary phase. If this multilayer ceramic capacitor employs, as a dielectric layer, a dielectric ceramic that contains barium titanate crystal grains in which part of Ba is substituted by Ca, Sr, or Zr, it is capable of suppressing the grain growth of crystal grains, and improving relative dielectric constant, temperature characteristic, and high-temperature load test characteristic, for example, in high-volume manufacturing using a tunnel type large kiln.

Thereby, a dielectric ceramics having high relative dielectric constant can be obtained.

摘要： A piezoelectric resonator having a resonator element in or on a substrate, said resonator element comprising a laminate of a plurality of piezoelectric ceramic layers and a plurality of electrode layers which are alternately laminated one upon the other, the piezoelectric ceramic layers neighboring up and down being set to oscillate in opposite phases relative to each other. In the piezoelectric resonator, the piezoelectric ceramic layers neighboring up and down undergo the thickness longitudinal oscillation in opposite phases, suppressing the oscillation of the fundamental mode and strongly exciting the oscillation of a mode of a high degree of not lower than the second degree. The piezoelectric resonator utilizing the mode of a high degree of not lower than the second degree is little affected by spurious caused by the oscillation of the fundamental mode.
