An antenna includes core-wire-side and ground-side feeding points aligned close to each other on a glass surface of a window of the vehicle near an opening of a metallic flange of the window; a ground-side element including a line extending from the ground-side feeding point in a direction away from a portion of the metallic flange which is located closest to the ground-side feeding point; and a core-wire-side element including a core-wire-side first line extending from the core-wire-side feeding point substantially in parallel with the line of the ground-side element, and a core-wire-side second line extending from the core-wire-side first line in a branched manner or extending directly from the core-wire-side feeding point in parallel with the core-wire-side first line. A length from the core-wire-side feeding point to a tip of the core-wire-side first line and a length from the core-wire-side feeding point to a tip of the core-wire-side second line correspond to two separate resonance frequencies within the frequency bandwidth to cause a resonance at each of the two separate resonance frequencies.
