Abstract

An amplifier includes an amplifier circuit configured to include a transistor that amplifies a signal, an insulating film provided over the amplifier circuit, an input pad provided over the insulating film and coupled to the transistor through a wiring in the insulating film, an output pad provided over the insulating film and coupled to the transistor through the wiring in the insulating film, and a metal layer provided over the insulating film to be grounded, and configured to include an opening that extends in a second direction intersecting with a first direction in a plane direction, the signal propagating from the input pad to the output pad in the first direction, and the opening being at a position overlapping the transistor.
