Abstract

An IC element 2 having an oscillation circuit and an amplification circuit is mounted on a wiring board 1, the IC element 2 is covered with a sealing resin layer 4 having a window 4a on an upper surface of the IC element 2, and a shielding layer 5 is made to adhere to the sealing resin layer 4 and the window 4a from above. In a simple configuration, the entrance of electromagnetic waves into the IC element 2 is reduced, which allows a transmission signal from the IC element 2 to be stabilized.
