Document Type and Number:
WIPO Patent Application WO/2019/004332
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce damage to a wiring board due to the provision of an inter-components shield, while maintaining the characteristics of the inter-components shield. A high frequency module 1a is provided with: a wiring board 2; a plurality of components 3a to d mounted on an upper surface 2a of the wiring board 2; a shield component 4 mounted between a component 3b and a component 3c; a sealing resin layer 5 which coats the components 3a to 3d and the shield component 4; and a shield film 6 which coats a surface of the sealing resin layer. An upper surface 5a of the sealing resin layer 5 is formed with a recess 10 in which the shield component 4 is exposed. The recess 10 is formed on the inside of an edge so as to not reach a side surface of the sealing resin layer 5. The shield film 6 coats a wall surface 10a of the recess 10 and further coats a portion of the shield component 4 that is exposed through the recess 10.
