Abstract
A surface shape recognition sensor of this invention has a surface protective film having a hydrophobic property on an insulating protective film which is made of an insulator and formed to cover a sensor electrode, and includes at least a ground electrode which is formed on the substrate such that the ground electrode is partly exposed on the surfaces of the insulating protective film and surface protective film so as to be insulated/isolated from the sensor electrode and come into contact with the surface of a detection target. This sensor prevents fingerprint residues from easily remaining and improves tamper resistance.
