Abstract

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.
