Abstract
A detector for detecting an object that may be feared to or about to be caught by a closing door such as a slide door of a vehicle incorporates a capacitance sensor with a directionality characteristic in the direction of its detection surface. The detector has a main body enclosing detection electrodes, an insulating material placed in between and a shield electrode serving to provide the directionality. A protective cover may cover the shield electrode and the detection electrodes. A water-repellant finish may be provided at least on a portion of the outer surface of the main body including the detection surface for preventing water drops from remaining or becoming larger. A plurality of mutually adjacent protrusions may be formed on the protective cover with thickness decreasing in the direction of protrusion for making it difficult for water drops to remain.
