A windshield includes a glass plate, a dielectric, and an electrothermal layer disposed between the glass plate and the dielectric. The electrothermal layer includes a conductive layer and strip electrodes having a resistance lower than a resistance of the conductive layer. The strip electrodes are disposed along at least two opposing outer edges of the conductive layer and are DC-coupled to the conductive layer such that the conductive layer is energized via the strip electrodes. The windshield further includes an antenna including a pair of electrodes disposed to face the electrothermal layer across the dielectric, and a slot at least a part of which is formed in one of the strip electrodes such that the slot is disposed between the pair of electrodes in plan view. One end of the slot is an open end that is open at an outer edge of the electrothermal layer.
