PROBLEM TO BE SOLVED: To improve durability and reliability of an antenna unit which is bent in conformity with the shape of a door handle of a vehicle.SOLUTION: An antenna unit 1A has at least an antenna 10, a detection electrode 20, and a circuit board 30 stored and held in an inner space formed of a case 40 made of flexible resin and a lid 50. The antenna 10 and circuit board 30 are arranged across a gap along a lengthwise direction of a door handle, the detection electrode 20 is arranged over from the side of the antenna 10 to the side of the circuit board 30, and a connection part 23 of the detection electrode 20 is soldered to the circuit board 30. The detection electrode 20 is provided with an elastic deformation part 22 at a part corresponding to the gap between the antenna 10 and circuit board 30.SELECTED DRAWING: Figure 2 |
