sensing device 1 are disposed inside the door handle 10 with reference to the position of the electrode 1 a thus the electrode 1 b is disposed below the electrode 1 a and opposite thereto and the drive detection circuit 1 c is provided at a circumferential location on the side or below the electrode 1 a and the electrode 1 b fig1 shows the detailed configuration of the contact sensing device 1 for the convenience of illustration the door handle 10 is appropriately cut only the circumference where the contact sensing device 1 is provided is taken out and the members of the contact sensing device 1 are shown by solid lines in a state in which the interior of the door handle 10 is seen through the region to be contacted by a user 39 s finger human body 20 in the door handle 10 is provided to be visible as a pad region 10 x the electrode first electrode la is mounted on the inner surface of a resin body with a thickness u03b4 that constitutes a case 10 a so that the resin body is interposed between the electrode and the outer case surface 10 a of the door handle 10 thus a distance equal to u03b4 is maintained between a site p on the pad region 10 x which is contacted by the finger 20 and the electrode 1 a the electrode 1 a is formed to have a surface area larger than that of the electrode 1 b and the electrode second electrode 1 b is fixed so as to be accommodated in a region directly below the electrode 1 a and arranged opposite thereto in fig1 the interior of the case.
