The dielectric substrate includes a flat portion on which an external terminal (T) to which a RFIC is connected is disposed, a flat portion in which the radiating element is disposed, a bent portion, a feeder, and a ground electrode (GND1). The feeder extends through the flat portions and the bent portion to connect the external terminal (T) and the radiating element to each other. The ground electrode (GND1) extends through the flat portions and the bent portion along the feeder. At the bent portion, a thickness of the feeder is greater than a thickness of the ground electrode (GND1). ## Claims ### Claim 1 An antenna module, comprising: a first radiating element; and a
