Patent ID: 8854061

Claim:
A linear sensor comprising: an attachment base attached to a metallic edge of an opening and closing body capable of opening and closing an opening disposed in a vehicle body, a skin cover part which bulges from the attachment base toward a peripheral edge side of the opening and includes a hollow part in the inside thereof, an insulator which includes flexibility and is embedded in the hollow part, and a plate-shaped electrode opposed to the attachment base, at least a portion of the electrode being embedded in the insulator, wherein a gap is disposed between the electrode and the attachment base in the hollow part, and the electrode is set in a plus pole and the attachment base is set in a minus pole as grounding, and proximity and/or contact between a foreign body and the skin cover part is detected based on a change in capacitance between the electrode and the minus pole, wherein a cover side projection protruding toward the insulator side is disposed in an inner peripheral surface of the skin cover part, and wherein the cover side projection is formed in a non-contact state with respect to the insulator.
