Abstract
A high frequency module incorporates a layered substrate, a plurality of elements mounted on a top surface of the layered substrate, and a metallic casing that covers these elements. The plurality of elements mounted on the top surface of the layered substrate include a band-pass filter element. The band-pass filter element includes a plurality of conductor layers for band-pass filter and a plurality of dielectric layers for band-pass filter that implement a function of a band-pass filter, but does not include any conductor layer that functions as an electromagnetic shield. A conductor layer for grounding that the layered substrate includes and the casing are each opposed to the band-pass filter element, and thereby function as an electromagnetic shield for the band-pass filter element.
