摘要： A sintered ceramic has a porosity of greater than about 30 percent and less than about 80 percent by volume. Pores are filled with an epoxy resin. A filling factor of the epoxy resin is about 40 percent by volume or more. A monolithic ceramic electronic component having an inner electrode, for example, a chip inductor is manufactured with such a porous sintered ceramic. When a direct current is superimposed, the resulting monolithic ceramic electronic component has a substantially unchanged self-resonant frequency and also has a rate of decrease in impedance of about 50 percent or less at 100 MHz.

摘要： A monolithic ceramic component includes a coil-including region formed by stacking ceramic green sheets for defining inner layers having a porosity of about 30% to about 80%, and outer layer regions formed by stacking ceramic green sheets for defining outer layers have a porosity of about 10% or less. Outer electrodes are provided on the right end surface and the left end surface of a sintered ceramic laminate. That is, the outer electrodes are provided on the main surfaces of outermost ceramic sheets for outer layers.

摘要： A monolithic ceramic electronic component includes a low-permeability coil portion formed by stacking low-permeability ceramic green sheets, a first coil and a relatively large number of pores, and a high-permeability coil portion formed by stacking high-permeability ceramic green sheets, a second coil and a relatively small number of pores. The first coil and the second coil are electrically connected in series to form a spiral coil. The coil portion composed of a ferrite ceramic having a small number of pores has a high permeability and a high dielectric constant, and the coil portion composed of a ferrite ceramic having a large number of pores has a low permeability and a low dielectric constant.

摘要： A connector having a housing with a cavity, a terminal fixed in the housing and a resistance board. The resistance board has an elastic insulating board and a number of conductors which are provided in the insulating board such that each conductor shows on an upper surface and a lower surface of the insulating board. The resistance board is inserted in the cavity of the housing so as to lie on an end portion of a flexible cable. A signal-transmitting conductor of the flexible cable is electrically connected with the terminal via the conductors of the resistance board.
