PROBLEM TO BE SOLVED: To provide a simple on-vehicle glass antenna whose sensitivity is high in a horizontal direction when attached to a vehicle. SOLUTION: The on-vehicle glass antenna 3 is formed on the surface of window glass for the vehicle. The on-vehicle glass antenna 3 comprises: a patch part 8 composed of a conductor; a grounding conductor 7 composed of a conductor formed on the same surface as the patch part 8 so as to surround the patch part 8; short-circuit lines 5a and 5b composed of a conductor connecting the grounding conductor 7 and the patch part 8; and slots 10a and 10b formed by being surrounded by the patch part 8, the grounding conductor 7 and the short-circuit lines 5a and 5b. When the maximum length in the horizontal direction of the patch part 8 is defined as A and the maximum length in a direction orthogonal to the horizontal direction along the window glass for the vehicle is defined as B, an aspect ratio A/B is 0.5 to 2.0.
