摘要： A monolithic ceramic component has inner electrodes which are thin having a thickness of from about 0.2 &mgr;m to 0.7 min, and thereby, delamination is inhibited even though ceramic layers are thin, having a thickness up to about 3 &mgr;m. The mean particle size of the ceramic grains of the ceramic layers is up to 0.5 &mgr;m, so that the concavities and convexities at the interfaces between the inner electrodes and the ceramic layers can be reduced. Preferably, metal powder in a paste used to form the inner electrodes has a mean particle size of from about 10 to 200 nm, and thereby, the metal filling ratio and the smoothness of the inner electrodes can be enhanced, and the coverage can be improved.

摘要： Disclosed herein is a heat reflecting sandwich plate made up of a first and a second transparent plates bonded together with a transparent resin film. The first transparent plate is coated on the inside thereof with a heat reflecting film which is a laminate composed of two metal oxide layers, with a noble metal layer intervening between them. The noble metal layer has a sheet resistance of 4-10 ohms/square. The first and second metal oxide layers have thicknesses controlled such that their ratio is in the range of 1.1 to 1.6. The heat reflecting sandwich plate produces reflected rays which have a chromaticness specified by -1.ltoreq.a.ltoreq.1 and -1.ltoreq.b.ltoreq.1, where a and b denote the chromaticness indices of Hunter's color specification system, and has a visible light reflectivity lower than 10%. Because of these characteristic properties, the heat reflecting sandwich plate has high strength and safety, exhibits outstanding heat reflecting performance, and assumes almost no color and looks good despite its comparatively high visible light transmittance.
