PROBLEM TO BE SOLVED: To provide a glass antenna which has improved receiving performance in each direction without causing degradation in directivity characteristics after H/V composition. SOLUTION: The glass antenna 1 includes a first antenna element (AM antenna element 20) composed of a plurality of horizontal conductors made orthogonal to one longitudinal conductor, a second antenna element (FM main antenna element 30) mounted on the first antenna element and capacitively coupled to a horizontal conductor positioned at the top part of a first antenna pattern, and a defogging electric heating heater (defogger 40) which is mounted under the first antenna element, and is composed of a plurality of horizontal conductors made orthogonal to the one longitudinal conductor capacitively coupled to a horizontal conductor positioned at the bottom part of the first antenna patter.
