The present invention relates to a method for producing a rare earth sintered magnet including the steps of: molding a mixture of magnetic powder containing a rare earth compound and oil-extended rubber containing oil and rubber to produce a molded body; removing the oil-extended rubber from the molded body; and calcining the molded body from which the oil-extended rubber is removed to produce a rare earth sintered magnet

Method for producing rare earth sintered magnet

A laminated ceramic electronic component includes a ceramic substrate, an internal electrode, and a buffer layer. The ceramic substrate includes a protective layer and a functional layer. The protective layer is disposed on at least one side of the functional layer. The internal electrode is embedded in the functional layer. The buffer layer is embedded in the protective layer and has a different burning shrinkage from the ceramic substrate.

Laminated ceramic electronic component

A laminated ceramic electronic component has a plurality of conductive layers embedded in a ceramic substrate. The laminated ceramic electronic component includes: a functional area composed of the plurality of conductive layers and ceramic layers interposed therebetween; and a protective area formed around the functional area to have a ring-like cross section. The laminated ceramic electronic component satisfies the following condition:0&#x3c;&#x2266;0.80,

Internal electrode layers are superimposed in a dielectric substrateat intervals. Step absorption layers are respectively provided on lateral sides of the internal electrode layers. A side portion of the internal electrode layer forms an inclined surface, and the step absorption layer is superimposed so as to partially overlap the inclined surface of the internal electrode layer. This is also applied to the other internal electrode layers and step absorption layers.

Multilayer electronic component and manufacturing method thereof

A laminated electronic component includes a ceramic body having an inner portion and a pair of outer portions disposed above and below the inner portion and a pair of external electrodes disposed on lateral sides of the ceramic body. A plurality of internal electrodes are embedded in the inner portion and alternately connected to the external electrodes. At least two layers of dummy electrodes are embedded in at least one of the outer portions and each connected to one of the external electrodes. An innermost one of the dummy electrodes has a same polarity as an adjacent outermost one of the internal electrodes. The dummy electrodes include at least one pair of adjacent dummy electrodes of opposite polarities.
