摘要： A module includes a capacitor composed of an insulating layer and electrodes, and a continuous spiral conductor, and a plurality of terminals formed in contact with the peripheries of the capacitor. The spiral electric conductor is composed of the same material as the terminals of the module. The spiral conductor has its axis parallel with the surface of the conductor layer that composes the capacitor. The module can include a plurality of capacitors inside. As a result, the module shows preferable electric properties compared to those according to the prior art. Since many kinds of filter circuits can be formed by slightly changing production conditions, this module is suited to the production of a variety of products in small quantity.

摘要： A method of manufacturing ceramic bodies comprising the steps of: preparing a ceramic sheet; forming through holes in the ceramic sheet, each of the through hole forming at least one part of the contour of each ceramic bodies; and cutting the ceramic sheet into pieces of ceramic bodies. The ceramic sheet can be a single ceramic sheet or a laminate of ceramic sheets. The method of manufacturing ceramic bodies further comprises a step of forming a recess in the ceramic sheet, or pressure molding or partially removing of the ceramic body, as required. The manufacturing method provides inexpensive production of small ceramic elements having a complicated shape and extremely smooth surfaces with less uneven filling and nonuniform density.

摘要： The electrical characteristic of the chip inductor is improved by preventing the occurrence of short circuits among the linear conductor sections of the coil section of the inductor by appropriately insulating the conductor sections from each other and, at the same time, the mounting surface of the exterior section of the inductor is flattened so that the inductor can be mounted accurately on an object. The chip inductor is provided with a prism-like main body (1) made of an insulating material, electrode sections (6) positioned to both end sections of the main body (1), the coil section (5) which is connected to the electrode sections (6) and, at the same time, positioned on the outer periphery of the main body (1) between the electrode sections (6), and the exterior section (9) coating the coil section (5) with an insulating resin (8). The coil section (5) has the linear conductor sections (3) and groove sections (4) formed by grooving a conductor layer (2) formed on the surface of the main body (1). The internal spaces of the groove sections (4) are also filled up with the insulating resin (8).

摘要： A composite component of the invention comprises a spiral strip of conductor and a plurality of terminals formed in close contact to an external periphery of a capacitor constructed of an insulation layer and electrode layers. The spiral strip of conductor is made of the same material as the terminals of the composite component. The composite component is characterized by its structure that a spiral axis of the spiral strip of conductor is in parallel with a plane of the electrode layers composing the capacitor. Also, the composite component of this invention is able to contain therein a plurality of the capacitors. Therefore, the composite component exhibits superior electrical characteristics not available from similar composite component of the prior art. Furthermore, a method of the invention is capable of manufacturing composite components containing a large variety of filter circuits without requiring a substantial change in the manufacturing condition. The method is therefore suitable for manufacturing the composite components of small quantity, but in numerous variations.
