Abstract:
A component built-in module includes an insulating layer (101), wirings (102, 106) integrated with both surfaces of the insulating layer (101), a via (103) connecting the wirings (102, 106), and one or more components (104) selected from an electronic component and a semiconductor, which is embedded inside of the insulating layer. In this module, at least one of the wirings (102, 106) is configured with a wiring (106) formed on a surface of a wiring board (109), and the components (104) embedded inside of the insulating layer (101) are mounted on and integrated with the wiring board (109) before embedding. This configuration allows the components such as a semiconductor to undergo a mounting inspection and a property inspection before embedding. As a result, the yields of the module can be improved. In addition, since the components are integrated with the wiring board and embedded, the strength thereof can be enhanced.

The above described arrangement provides the dielectric filter with an improved Q factor of a resonator, a low loss, and a high attenuation.
