An antenna module is an antenna module including at least a first radiation electrode, and a first power feeding electrode coupled with the first radiation electrode, and includes: a first dielectric layer including the first power feeding electrode; and a second dielectric layer disposed at one side of the first dielectric layer in a thickness direction of the first power feeding electrode, and a fracture toughness value of the second dielectric layer is larger than a fracture toughness value of the first dielectric layer.
