To prevent an antenna attached to an end part of a substrate from easily falling off the substrate.
A flat part which can be sucked in vacuum by an automatic mounting machine is provided on an upper surface of the antenna 11. A lower surface of the antenna 11 includes a step-shaped part. The substrate 12 consists of a high frequency circuit and the like and is a circuit board and the like where the antenna 11 is mounted. A notch part CA with which a projection part SA of a step-shaped part on a lower surface of the antenna 11 is engaged is formed on one side of the substrate 12. A recessed part DA of the step-shaped part of the antenna 11 is abutted on an abutting part MA of the substrate 12. A part of the abutting part MA which is adjacent to both ends of the notch part CA is an engaging part EA. The engaging part EA blocks rotation around a shaft of the antenna 11 having a side of a substrate end part where the antenna 11 is mounted as a rotary shaft.
