Patent ID: 11178778

Abstract:
A high frequency module 1a includes a wiring board 2, multiple components 3a to 3d mounted on an upper surface 2a of the wiring board 2, a shield component 4 mounted between the component 3b and the component 3c, a sealing resin layer 5 that covers the components 3a to 3d and the shield component 4, and a shield film 6 that covers the surface of the sealing resin layer. A recess 10 is formed in an upper surface 5a of the sealing resin layer 5 so as to expose the shield component 4. The recess 10 is formed within a region surrounded by edges of the sealing resin layer 5 so as not to reach the side surfaces of the sealing resin layer 5. The shield film 6 further covers wall surfaces 10a of the recess 10 and part of the shield component 4 exposed through the recess 10.
