Beschreibung
Zusammenfassung:	A high frequency module improved in heat dissipation performance includes: a dielectric multilayer substrate including a ground layer and a high frequency electronic component mounted thereon while being in contact with the ground layer, the high frequency electronic component including a heat generating portion; and a cutoff block formed of an upstanding wall portion and a cover portion covering the upstanding wall portion, the cutoff block housing the high frequency electronic component and including a hollow portion having a cutoff characteristic at a frequency of a high frequency signal used by the high frequency electronic component, and the upstanding wall portion of the cutoff block being in contact with the ground layer of the dielectric multilayer substrate.
