摘要： Provided is a flexible, durable capacitive sensor that achieves high flexibility in designing wiring arrangement. A capacitive sensor includes a dielectric layer and a plurality of electrode units placed on both sides of the dielectric layer in the front-back direction. The electrode unit includes an insulating layer having through holes extending therethrough in the front-rear direction, electrode layers placed on one side of the insulating layer in the front-back direction, and jumper wiring layers placed on the other side of the insulating layer in the front-back direction and electrically connected to the electrode layers through the through holes. The insulating layer has an elongation at break of 60% or more, a tension set of less than 5%, and a volume resistivity of 1.0×1010 Ω·cm or more.
