In a vehicle glass antenna in which an antenna conductor, a feeding portion which is connected to the antenna conductor, a parasitic conductor and a ground portion which is connected to the parasitic conductor are provided on a window glass, when the window glass is installed in a vehicle, the feeding portion constitutes a portion where the antenna conductor is electrically connected to a signal processing circuit installed in the vehicle, and the ground portion constitutes a portion where the parasitic conductor is electrically connected to a vehicle body, the feeding portion and the ground portion are disposed so as to be aligned along a reference direction, the antenna conductor comprises: a first element which extends from the feeding portion as a starting point in a first direction which is a direction which is parallel to the reference direction and which is directed to an opposite side to the ground portion; a second element which is connected to a first terminating portion which constitutes an end of the first element which lies opposite to the feeding portion and which extends in a second direction which is at right angles to the first element and which is directed inwards of an outer circumference of the window glass; and a third element which extends from the second element as a starting point in a third direction which is a direction opposite to the first direction, and the parasitic conductor comprises a parasitic element which constitutes an element at least part of which extends from the ground portion as a starting point in the second direction.
