IPC: H01G4/12
Filed: 1991-09-27
Abstract: PURPOSE:To prevent displacement of internal electrode pattern, ununiformity of internal electrode thickness and lowering of contact strength in the vicinity of the part to form the internal electrode by forming internal electrode on a ceramics green sheet having a dent in the area in which internal electrode is formed. CONSTITUTION:A conventional laminated ceramics element uses a smooth green sheet 1 to form an internal electrode 2. Therefore, only the internal electrode 2 forming part is protruded and this protruded part is then excessively compressed in the post process. Accordingly, such a laminated ceramic element has drawbacks that a pattern of internal electrode 2 is displaced, thickness of internal electrode 2 is ununiformed and contactness of the area near the part to form the internal electrode 2 is lowered. A laminated ceramic element preventing drawbacks of the conventional element is herein realized by utilizing a ceramics green sheet 1 including the part which is uniformly indented to form the internal electrode 2 and then forming internal electrode thereon.

Abstract: PURPOSE:To prevent the effect due to the vibration mode and to decrease the series resonance resistance (CI) even when front and rear side electrodes are formed while the position of them is deviated by selecting the distance between conductive electrodes for an exciting electrode and a support electrode placed on a front and a rear side respectively so as to satisfy a required condition.
