Abstract
A high-frequency device package includes a base, a high-frequency device mounted on the base and having a power supply electrode, a signal electrode, and a ground electrode disposed on a surface thereof, a plurality of leads electrically connected respectively to the power supply electrode, the signal electrode, and the ground electrode using a tape carrier, and a resin body sealingly encasing the high-frequency device. The resin body is formed by dropping a molten resin mass onto the base in covering relation to the high-frequency device and thereafter solidifying the dropped resin mass to sealingly encase the high-frequency device.
