る。Conventional technology For example, when coupling occurs between the antenna tuning circuit and the local oscillation circuit of a superheterodyne receiver, if their frequencies are close, a pull-in phenomenon may occur or the oscillation voltage may be radiated through the antenna circuit. There was a problem that the light was radiated to the outside and caused interference. For this reason, in the past, circuits such as those described above were placed apart from each other physically, or one circuit was covered with a shield plate to avoid coupling with each other, but such a configuration made it difficult to downsize. There was a limit. On the other hand, as a means of downsizing circuits, it is common practice to use composite components. For example, in the case of a multilayer capacitor, if a plurality of capacitors have the same capacitance value, the plate areas are approximately the same, so it is possible to manufacture them as an integral structure.
