Abstract
In the high-frequency module of the present invention, an insulating resin is formed so as to seal a high-frequency semiconductor element mounted on a surface of a substrate and further to seal electronic components. Furthermore, a metal thin film is formed on the surface of the insulating resin. This metal thin film provides an electromagnetic wave shielding effect.
