A capacitance touch sensing device that detects the touch of a user against a surface of a door handle on the outside of a vehicle includes an upper sensor electrode provided in an upper portion of the door handle, a lower sensor electrode provided in a lower portion of the door handle, an upper detecting portion that detects when the user has touched an upper surface of the door handle based on output from the upper sensor electrode, and a lower detecting portion that detects when the user has touched a lower surface of the door handle based on output from the lower sensor electrode. The detection sensitivity of one of the upper detecting portion or the lower detecting portion is lower than the detection sensitivity of the other.
