Abstract
A linear sensorincludes an attachment baseattached to a metallic edge of a slide doorcapable of opening and closing a platform, a skin cover partwhich bulges from the attachment baseand has a hollow partin the inside, an insulatorwhich has flexibility and also is embedded in the hollow part, and a plate-shaped electrodeopposed to the attachment base, at least a portion of the electrode being embedded in the insulator. In the hollow part, a gapis disposed between the electrodeand the attachment baseand also, the electrodeis set in a plus pole and the attachment baseis set in a minus pole as the grounding, and proximity and/or contact between a foreign body and the skin cover partis detected based on a change in capacitance between the electrodeand the grounding minus pole.
