Abstract
A high-frequency module of the invention includes an insulating substrate including a plurality of ceramic thin plates stacked in layers, and an insulating layer formed on the top surface of the insulating substrate. In the high-frequency module, a thin-film circuit is formed on the top surface of the insulating layer, and comprises a wiring pattern and an electrical part comprising a resistor and/or a capacitor. The wiring pattern is formed of a thin film. The electrical part is connected to the wiring pattern and is formed of a thin film. Therefore, the electrical part of the high-frequency module of the invention can be formed more precisely than an electrical part of a related high-frequency module. Consequently, it is possible to provide a high-frequency module having high performance.
