摘要： PURPOSE:To raise a resonance frequency by reducing parasitic inductance of electrodes by specifying an interval between the internal electrode and the signal internal electrode. CONSTITUTION:There are formed on a sheet a ground internal electrode 1 and a signal internal electrode 2 for provision of a through type laminated capacity by making use of a screen printing process. The sheets after printed are laminated with proper pressure, and are divided for each capacitor element, and are thereafter sintered. The sheets are laminated such that a distance between the electrodes 1, 2 after the sintering is 30mum or less. The capacitor is yielded by forming external electrodes 4-6. Hereby, in the feedthrough type laminated ceramic capacitor having a higher resonance frequency, it is possible to deal with the need of the capacitor getting a further higher frequency response. Further, no limitation is applied to a packaging structure of capacitors and other elements on a substrate.

摘要： PURPOSE:To avoid the reduction in the effective area of a substrate by exposing the conductor of a circuit baked in closing at a ground face provided on a corner of the substrate. CONSTITUTION:A conductor (resonance element) 10 is arranged so that its connection terminal is positioned at one corner of a substrate block 13, and the corner is ground after the grinding of blocks to expose the connection terminal of the resonance element 10 to the ground face 13a, Then the connection is made to a conductor of other layer or an external circuit by providing a connection conductor 15 onto, at least the ground face 13a for the electric connection to the exposed connection terminal. Thus, the corner of the block 13 is ground and removed to form the ground face 13a and a part of the conductor 10 is exposed to the ground face 13a, then the area for grinding and removal is less and the connection electrode is formed without changing largely the effective area of the substrate.

摘要： PURPOSE:To bring a temperature coefficient of a high frequency dielectric material close to zero by mixing an oxide aggregate having a positive temperature coefficient of dielectric constant, another oxide aggregate having a negative value thereof, and glass with each other. CONSTITUTION:Glass, an oxide aggregate having a positive temperature coefficient of dielectric constant, and another oxide aggregate having a negative value thereof are mixed with each other at a specified blending ratio to constitute a high frequency dielectric material. Accordingly, a temperature coefficient of the high frequency dielectric material can be brought close to zero, and when this material is used for a resonator, a temperature coefficient of resonance frequency can be brought close to zero. It is desirable that the oxide aggregate having a positive temperature coefficient of dielectric constant is composed of one or more kinds of aluminum oxide and magnesium titanate and the oxide aggregate having a negative value thereof is composed of one or more kinds of calcium titanate, strontium titanate, and titanium oxide, however, the aluminum oxide and titanium oxide are not simultaneously included.
