多くなるという問題をもっていた。Conventional configurations and their problems In recent years, the demand for smaller and lighter electronic devices has increased, and along with advances in high-density packaging technology, the use of chips for electronic circuit components is progressing. Furthermore, with regard to passive components such as coils, capacitors, and resistors, attempts are being made to combine them, for example by accommodating a capacitor and a resistor in one package. Among the passive components mentioned above, a combination of a coil and a capacitor is often used, and many proposals have been made regarding LC composite components. These include, for example, those in which a single coil and capacitor are simply integrated using resin or the like, and those in which the coil and capacitor are made using a printed lamination method and then combined on separate substrates. However, the former has a large volume and is difficult to make into a chip, so it is not compatible with recent high-density packaging technology. ! However, the latter method had the problem of requiring a large number of man-hours.
