Abstract: An antenna (101) includes a grounded conductive foil (110) disposed on a module substrate (140), a first conductive foil (111), and a second conductive foil (112). The first conductive foil (111) and the second conductive foil (112) are disposed on the module substrate (140), are elongated, and do not overlap with the grounded conductive foil (110) in a plan view of the module substrate (140). The first conductive foil (111) has one end supplied with an antenna signal and the other end that is open. The second conductive foil (112) has one end connected to the grounded conductive foil (110) and the other end that is open. A wireless module (120) includes a circuit unit (130) including a communication circuit and provided to the module substrate (140) on which the antenna (101) is formed.
