ABSTRACT:
A core member includes a cylindrical body. An antenna element is disposed on an outer peripheral face of the cylindrical body. A first engagement member is provided on the outer peripheral face of the cylindrical body. A cap member includes a peripheral wall fitted over the core member so as to cover the antenna element. A second engagement member is provided on an inner peripheral face of the peripheral wall to engage with the first engagement member. A restraining member is brought into contact with an outer peripheral face of the peripheral wall of the cap member to prevent the peripheral wall being deformed outward. The restraining member is opposed to at least a position where the second engagement member is provided.
