To provide a resilient tube having a pressure sensor function itself, with excellent detection sensitivity of pressure.

This resilient tube 10 having the pressure sensor function is formed into a tube shape with a coil-like carbon fiber dispersed in an elastic material. The pressure applied onto a surface is detected by the dispersed state of the coil-like carbon fiber. The detection sensitivity of the pressure is enhanced by using as the elastic material a resin having 20 or more to less than 50 of JIS A hardness specified by JIS K6301. Mechanical strength of the resilient tube 10 is enhanced by using as the elastic material a resin having 50 or more to 100 or less of JIS A hardness specified by JIS K6301.
