PURPOSE:To obtain an on-vehicle antenna without any projection part such as a whip antenna and offering good visual field for driving such as a glass antenna by utilizing a slope of a door biser of a cabin. CONSTITUTION:The door biser 4 consists of a horizontal part 43 and a slope 44 and a metallic part 41 is fitted to a door 2 as a side 42 and the rest is made of a non-metal. Then an antenna 5 is formed to the non-metallic part of the slope 44 and grounded by the metallic part 41. Since the metallic part 41 is stuck closely to a door frame 21, the part 41 is grounded through the car body. Then it is not required to draw a ground wire of the antenna 5 to the door 2. Since the antenna 5 is formed at the slope 44, the antenna is used for both vertical and horizontal polarized waves. Thus, the on-vehicle antenna having no projected part and giving no hindrance the visual field of driving.
