To mount an antenna to a dielectric body without deteriorating excellent appearance, and also to obtain a sufficient half-value angle.
An antenna 1 includes: a rectangular, thin, and planar conductive body 11 mounted to glass 10; and an antenna part 12 composed of a rectangular loop and a power feeding part 13 which are enclosed by the conductive body 11. The glass 10 may be the window glass of a vehicle, for example, and the conductive body 11 may be constituted by allowing a thin film shape metallic plate to adhere on one surface of the glass 10. The antenna part 12 and the power feeding part 13 may also be constituted by allowing the thin film shape metallic plate to adhere on one surface of the glass 10. The gain of the antenna 1 is raised and also the half power angle is made to be a wide angle by the work of the conductive body 11.
