Patent ID: 11302606

Abstract:
A high-frequency module 1a includes: a circuit board 2; a first component 3a, which has characteristics likely to be changed by heat, and a second component 3b, which generates heat, that are mounted on an upper surface 20a of the circuit board 2; a sealing resin layer 4 configured to cover each of the components 3a and 3b and a component 3c; a shield film 5 configured to cover a surface of the sealing resin layer 4; and a heat dissipation member 6 disposed above an upper surface 4a of the sealing resin layer 4. A recessed portion 11 is formed in the upper surface 4a of the sealing resin layer 4 as viewed in a direction perpendicular to the upper surface 20a of the circuit board 2. The recessed portion 11 can prevent the heat generated from the second component 3b from affecting the first component 3a.
