PROBLEM TO BE SOLVED: To provide a touch sensor having a high degree of bending freedom and identical detection sensitivity independently of directions without causing shape deformation or increase of detection load when it touches a big object. SOLUTION: The touch sensor 51 includes an inside electrode 53 formed linearly with a flexible conductor inside an outside electrode 52 formed tubular with a flexible conductor. A spacer member 54 formed spirally with a flexible conductor is provided between the outside electrode 52 and the inside electrode 53. This spacer member 54 provides a clearance between the outside electrode 52 and the inside electrode 53. The spacer member 54 is formed cylindrical with an air gap 54a in the space and to have a flexibility. An inner conducting wire 55 is buried in the center of the inside electrode 53. The inner conducting wire 55 is a stranded wire of a resin wire 55a and a conducting wire 55b and the conducting wire 55b is wound spirally around the core. This makes the inside conducting wire 55 retractile. COPYRIGHT: (C)2009,JPO&INPIT
