摘要： An actuator includes a fired ceramic substrate having a space opened downward, a first electrode formed on the upper surface of the fired ceramic substrate above the space, a piezoelectric/electrostrictive body formed on the first electrode so that the volume changes with input and output of electric power, and a second electrode formed on the piezoelectric/electrostrictive body. The piezoelectric/electrostrictive body is composed of Pb(Zr1-xTix)O3 or (Li, Na, K) (Nb, Ta)O3 as a main component and contains crystals oriented along the direction of an electric field. In the actuator, the degree of orientation of the piezoelectric/electrostrictive body can be increased regardless of the orientation of the substrate on which the piezoelectric/electrostrictive body is formed.

摘要： A fuel cell has a stack structure in which fired sheet bodies (laminates each including a fuel electrode layer, a solid electrolyte layer, and an air electrode layer) and support members for supporting the sheet bodies are stacked in alternating layers. Each of the sheet bodies is warped downward (toward an air-electrode-layer side). Because of a magnitude relationship of thermal expansion coefficient among the layers in the sheet body and that between the support member and the sheet body, a warp height gradually lessens in the course of temperature rise at start-up. However, even when a working temperature (800° C. or the like) is reached, the sheet bodies are still warped downward. By virtue of presence of the warp, the sheet bodies become unlikely to be deformed at the working temperature.

摘要： A thin plate member is a thin plate member that is formed by sintering, contains a ceramic layer, and comprises a thin part having two or more types of layers laminated, each of which is made of a material having a different thermal expansion coefficient, and a thick part that is made by laminating plural layers including at least all of the layers constituting the thin part, and has a thickness greater than the thickness of the thin part. The thin part has a shape warping in the direction perpendicular to the plane of the thin plate member. By virtue of this configuration, the internal electrical resistance of the thin part can be reduced. Further, the thin plate member can be provided that is difficult to be deformed with respect to the internal stress caused by the difference in thermal expansion coefficient between layers.
