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： A composite component of the invention has a structure of laminating a coil composed of at least one layer of conductor layer and at least one layer of insulator layer, and a capacitor composed of at least one layer of electrode layer and at least one layer of dielectric layer. And, it also includes, if necessary, an internal conductor for electrically connecting the coil and capacitor. Further, plural coil elements and capacitor elements are provided in a same layer. According to such constitution of the invention, composite components having various types of filter circuits can be manufactured easily by slight process condition changes. As a result, composite components for noise reduction can be mass produced efficiently, and a high productivity is obtained.
