PROBLEM TO BE SOLVED: To provide a capacitance type touch pad capable of sufficiently suppressing the reduction in detection sensitivity by further reducing the number of lines of electric force absorbed by a ground electrode.SOLUTION: The capacitance type touch pad includes: a substrate 2; a drive electrode pattern 4 disposed on the substrate 2; a detection electrode pattern 7 disposed on the substrate 2 so that the detection electrode pattern 7 does not overlap the drive electrode pattern 4 in the top view; and a ground electrode pattern 9 disposed on the substrate 2 so that the ground electrode pattern 9 does not overlap the drive electrode pattern 4 in the top view. The drive electrode pattern 4 and the detection electrode pattern 7 are disposed on the top side of the substrate, and the ground electrode pattern 9 is disposed on the lower surface side of the substrate and obliquely under the drive electrode pattern 4 with respect to the substrate 2. |
