摘要： The object of the present invention is to provide an exhaust gas purifying catalyst that can achieve high purification performance while suppressing H2S emissions. The object is solved by an exhaust gas purifying catalyst in which the lower layer of the catalyst coating layer comprises a ceria-zirconia composite oxide having a pyrochlore-type ordered array structure, in which the ceria-zirconia composite oxide contains at least one additional element selected from the group consisting of praseodymium, lanthanum, and yttrium at 0.5 to 5.0 mol % in relation to the total cation amount, and the molar ratio of (cerium+additional element):(zirconium) is within the range from 43:57 to 48:52.

摘要： A multilayer capacitor comprises a capacitor element body constituted by a plurality of laminated dielectric layers; first and second signal terminal electrodes and a ground terminal electrode which are arranged on an outer surface of the capacitor element body; and a ground electrode, first and second signal electrodes, and an intermediate internal electrode which are arranged within the capacitor element body. The first signal electrode is connected to the first signal terminal electrode, while the second signal electrode is connected to the second signal terminal electrode. The ground electrode is connected to the ground terminal electrode and has a first region overlapping the first signal electrode in a first direction in which the plurality of dielectric layers are laminated and a second region overlapping the second signal electrode in the first direction. The intermediate internal electrode is arranged such as to be separated from the first and second signal terminal electrodes and the ground terminal electrode and positioned between the first signal electrode and the ground electrode and between the second signal electrode and the ground electrode. The intermediate internal electrode has a region overlapping the first region in the first direction and a region overlapping the second region in the first direction.
